Pasta with aubergine, basil, chilli and pine nuts

Pasta is funny stuff. On the one hand, it's been the staple of student diets, in one form or another, for years. Often just served with grated cheese as it's cheap, filling and quick. At the other extreme, it's the lynchpin of the cuisine of an entire country where it can be covered in all sorts of over-priced shit, like truffles or caviar for fuck's sake. Yet another example of the gentrification of what has been a peasant food for centuries, a subject I've already ranted about.

Let's face it, pasta is usually nothing more than wheat and water, pressed into some fancy shapes. Obviously this belies the long culinary history of pasta. all the way from Italy. There are estimated to be over 350 varieties of pasta, many of which named after a dizzying array of things. Body parts seem a common theme with ears (orecchiette), tongues (linguine), moustaches (mostaccioli, another name for penne) all having pasta shapes named after them. Invertebrates get a bit of a look in too, with snails (lumache), squid (calamarata), worms (vermicelli) and butterflies (farfalle) all having a starring role. Then there is the really odd like bibs (bavette), cooking pots (lasagne) and thimbles (ditalini). Sadly there aren't any obviously rude official regional pasta varieties, as would fit the nature of this blog, though, as I pointed out previously, the word penne is just one "n" too many away from meaning penis. Then, I consulted everybody's friend Google and found that there is actually a dick-shaped pasta variety.

Al dente

Anyway, moving back to the recipe in hand, when considering vegetarian dishes, pasta is a perfect base and the Italian love of fresh vegetables make for some delicious possibilities. This concoction is no exception and really is a cracking little recipe. Aubergines, garlic, chilli, basil and a few crunchy pine nuts mean it's stupidly simple and quick to put together. 

TIMING
Preparation: 5 minutes
Cooking: 30 minutes

INGREDIENTS
4 tbsp olive oil plus additional for pouring on
2 tbsp pine nuts
4 cloves of garlic, crushed
1 large aubergine (around 300g in size), chopped into 2cm dice
2 tbsp tomato puree
1 tsp dried chilli flakes
Salt and black pepper to taste
Handful of fresh basil leaves
150-200g dried pasta (penne or fusilli work)


RECIPE
Heat the oil in a large pan and throw in the pine nuts

Fry them for a couple of minutes, until they are golden brown before removing them with a slotted spoon

Add the garlic to the hot oil and fry for 2 minutes before adding the aubergine.

Fry for another 10-15 minutes until the aubergine pieces start to colour

Add the tomato puree, black pepper and salt to taste and continue to cook for another 10-15 minutes, adding the odd tablespoon of water if it gets too dry

Meanwhile, cook the pasta and drain.

Turn the pasta into the pan with the cooked aubergine, mix, and add the pine nuts.

Finally, tear the basil leaves and add to the pasta and aubergines and stir, adding additional olive oil to give the dish a glossy look.

Serve up with some nice crusty bread.



NOTES
Probably because my pedigree is more factory-made by Clarks in northern England than hand-made in Milan, I don't have much time for the whole idea that a certain shape of pasta must be served with a certain type of sauce. In this instance, the dried penne and fusilli I used (there was half a portion of fusilli left so had to add some penne from a new packet) held onto the sauce well. I've also served this with fresh tagliatelli and it works just as good.

The basil and pine nuts really make this dish. Dried basil is not a substitute for fresh leaves as the taste is very different. Pine nuts could possibly be swapped for other nuts, perhaps peanuts or cashews, but the dish will be missing the subtle coniferous fragrance that they impart.

One rare problem with pine nuts is pine mouth syndrome. This can happen after eating some pine nuts when, as I found out one time, you end up with a bitter taste in your mouth for a few days after eating the kernel. It does fade, but you don't enjoy your dinners for a few days as a result.

Contrary to urban myth, pasta was not brought to Italy by Marco Polo coming back from China, but by Arabs from North Africa. Is nothing sacred? Next thing you know they'll be claiming Arabs gave the world mathematics like algebra or made early advances in astronomy. Oh, wait, they did.

Pasta with ham and mushrooms

Time for a sweary confession. It's hopefully obvious from this blog that I really love food and, more, that I'm fairly discerning about what I eat. I believe that great meals need good quality ingredients. All this is true, but I absolutely fucking adore pork scratchings. Pig rind, pork crackling, pork crunch, call it what you will, but in my opinion scratchings are the food of the fucking gods. Quite honestly, to me, scratchings are the ambrosia (no, not the rice pudding, you knob) to the nectar (no, not the loyalty scheme, you knob) that is beer. I would live on them if I could, though you would definitely be well advised to stand upwind of me if I did as they do not make a pleasantly aromatic bedfellow with my gut microflora.

I'm so much of a scratchings nerd it's often the second thing I look for in a new pub, after what beer they do. The most exotic of these was when I was getting pissed on San Miguel (Filippino version, not the Spanish version. They are supposed to be the same but they taste very different) it is in a small beach bar in Manila (in a street, not on a beach). They had vendors coming round to sell all sorts of weird things including knock-off watches, knock-off viagra (at least I assume it was knock-off) and even live snakes. Then a guy appeared who was selling actual pork scratchings which were fantastic. Of course, scratchings are also quite possibly the very worst thing you can actually eat: thick with fat, caked in salt and can shatter your teeth if you get bad batch. And don't even get me started on the smell that literally farts from the bag when you open it. Negative points aside, the point of all this is that, with all due respect to my vegetarian, Muslim and Jewish friends, surely pigs are meant to be eaten if even their packaging tastes so fantastic.

Filipino pork scratchings!

Obviously, there is far more to (from?) the pig than scratchings. There is a phrase from Spain saying they use "everything but the squeal" from the pig, (which is also the title of a book by a British expat living in Galicia), in that pretty much the entire animal is used in some way. If you think about it, there are a multitude of things derived from the original pig. Scratchings I've already mentioned, then there's bacon, sausages of various types, uncured pork meat in various forms, a whole anatomy of offal and even the blood in the form of blackpudding. There are less "meaty" products like lard and suet, then there are other uses for pigskin as leather and gelatine. Let's also not forget a wealth of medical uses: porcine insulin is used in treating diabetics and pig skin can be used to make dressings to treat burns patients. Pig products even find their way into cosmetics

I couldn't do a comedy/cookery blog mentioning Spam and not put this, could I?

One of the greatest product of the pig is ham. Like any food, ham can vary from the sublime, like Jamon Iberico from Spain, to the revolting, like tinned spiced ham otherwise known as Spam (so bad they named nuisance e-mail after it). In fairness, Spam is not a good representation of actual ham since it is at least partially mechanically recovered meat and not entirely pig in origin. Generally, real ham tastes good however much you pay for it.This is especially true if you intend to use it in a recipe like this rather than stick it in a sandwich. True, cheaper versions are pumped full of water so you're getting less meat per penny, but the flavour should still be there which, for the purposes of this recipe, is all you need.

This is yet another cheap, quick and easy meal. These factors are all well and good, and they form a bit of a theme in many of my blog entries. The most important thing, however is that this dish really tastes fucking fantastic which is a more prominent theme I hope runs through every single one of my recipes.

INGREDIENTS
1 tbsp olive oil
1/2 red onion, finely chopped
3 cloves of garlic, crushed
100g chestnut mushrooms roughly chopped
150g cooked ham, roughly chopped (smoked if you prefer)
pinch of fennel seeds
pinch of mixed herbs
dash of lemon juice
1/2 a vegetable stock cube
100ml red wine
100ml pasata
Black pepper
All ready to cook
From 9 o'clock: ham, mushrooms, garlic, red onion

RECIPE
Heat the oil in a good heavy pan and add the onion and garlic.
Slowly cook the onion for 5-10 minutes then throw in the mushrooms.

Keep sauteing until they are cooked and add the ham to warm through.

Add the fennel seeds, herbs and lemon juice before crumbling in the half stock cube.

Pour in the wine and pasata and stir well, adding freshly ground black pepper. Leave to simmer for 5-10 minutes.

Serve on pasta. Tagliatelle works quite well

Ready to eat

NOTES
You can use smoked or regular ham. The tastes are different but both make a great dish.

For the version I took photos of for this recipe I used a cheap off-cuts pack of smoked ham from my local super market. It's not going in a sandwich and you're chopping it up so the original form doesn't matter too much and this was also quite cheap.You could use panchetta if you were feeling particularly foodie wankerish but it is a little over-powering in this dish.

I'm glossing over the recent WHO report naming  processed meat products such as ham as carcinogenic.

Yet again I need to point out that, while my regular blog guest star, Rick Stein, may mention being somewhere exotic like the Philippines in his painfully meandering stories, he probably wouldn't be talking about getting rat-arsed on cheap local beer and being offered drugs to give you a prolonged stiffy, or indeed pork scratchings. Sweary Chef wins again.

Mince wonder part 3: Bolognaise

It was only a matter of time before I got round to posting my version of this old kitchen standard and it's yet another addition to my array of mince wonders following chilli con carne and shepherds' pie. Mince doesn't cost a lot and can also be replaced by veggie mince if necessary, making it flesh-dodger friendly, so this dish is really versatile, tasty and cheap. It's the ultimate student/laddish meal but nice enough for a more sedate dinner with polite company.

It's a cliché to refer to the 1970s as the decade that style forgot, but this isn't really fair. Sure, the fashion was largely pretty ludicrous, but this was also the decade that gave us punk and decimalisation. It's also the time when we Brits started to look to our new European chums for food and style tips. These aspirations to European cool may have left a lot to be desired by today's standards, but then again, you do need to learn to shit in a potty before you can use the toilet.

70s fashion
This much polyester in one location is now banned due to the fire risk

In the 1970s spaghetti bolognaise was the absolute fucking zenith of continental sophistication. In fact this dish is so 70s you could put a droopy moustache on it and call it Peter Wyngarde. I know it's easy to scoff with the benefit of hindsight, but its competition in terms of continental sophistication at the time included crème caramel in plastic potsColman's Beef Bourgignon ready-made sauce mix in a sachet; and Blue fucking Nun Liebfraumilch German white wine, so it won hands down on being something that tasted nice.

Label from a Blue Nun bottle
and a video giving correct response to being offered this awful excuse for wine

Anything from mainland Europe was considered stylish. Even British cars of the time had an aura of continental mystique about them with names like Allegro, Cortina and Capri. This was, of course, long before our era of Easyjet and Ryanair flights, the Channel Tunnel and the EU. This was an age when these places across the Channel in Europe were exotic and sophisticated. They were separated from us by water, they were "other". These countries were so exotic you needed visas to enter them, so sophisticated that you could get ameobic dysentery from merely looking at a glass of the local tap water (or so travel advice of the time would lead you to believe).

Europe had an edge, it seemed a dangerous place. There was often a pervading mistrust of Germany from those who had lived through WWII. France ate funny-shaped bread, molluscs and amphibians. Spain was just recovering from being under a Fascist dictatorship and was on the verge of a military coup in order to return it to one at any time (yes, this really almost happened).

Nowadays things are different. Forty years on and we find that we Brits are more worldly wise. Foreign travel is nothing we think twice about. We pay the price of a pint of Belgian lager (brewed under licence in Wales) allowing us to be herded onto a 737 to Barcelona or Bratislava for a weekend. We get there and immediately find an Irish pub to get shit-faced on Guinness while watching the Man U game before getting a Big Mac on the way back to our hotel to crash out before a full English in the morning to dissolve the hangover. Like I said, exotic and oh-so-fucking worldly.

As I've alluded to in other blog entries, this was my very first taste of Italian food. As I've also alluded to, I was raised in a house that was hardly an outpost of culinary exploration. Bolognaise in my family went through various incarnations as I grew up though, in fairness, many of them were actually quite tasty if not authentically Bolognaise. For example, baked beans don't really grow on trees in the fair city of Bologna, but did find their way into some of my parents' incarnations of this ragout but made for a reasonably palatable dinner. My version is a bit more authentic and certainly doesn't have baked fucking beans in it.

INGREDIENTS
500g beef mince (or vegetarian mince if you are so inclined)
2 tbsp olive oil
1 large onion, finely chopped
1 stick celery, finey chopped
1medium carrot, finely chopped
4 large cloves of garlic, crushed
250g mushrooms, coarsely chopped
2 tins of tomatoes (or replace 1 tin with a 500g carton of pasata)
2 table spoons of tomato puree
1 tsp mixed, dried herbs
1 bay leaf
1 tsp paprika
Freshly ground black pepper to taste
1 beef stock cube
150ml red wine
2 tsp balsamic vinegar
2 tsp Worcester sauce
Dash of Tabasco sauce (optional)
2 tsp dark soy sauce

RECIPE
The vegetables
Carrot, celery, garlic, onion and mushrooms.
Note how finely chopped they are, apart from the mushrooms

In a heavy saucepan dry-fry the mince to brown it for about 5 minutes (essentially until it's cooked), making sure it's well broken up with no lumps, and pour it into a sieve to get rid of the excess fat.

To the empty pan add the olive oil and heat on medium before adding the onion and garlic to fry for 5 minutes.

Throw in the celery and carrot and gently cook for 10 more minutes, ong enough to soften, then add the mushrooms for another 5 minutes until they look cooked.

Return the cooked mince to the pan and add the tomatoes, breaking them up (or use chopped tinned tomatoes), before stirring well and adding the herbs, bay leaf, paprika, black pepper and mix well.

Crumble the stock cube in and squirt in the tomato puree, again stirring well.

Pour in the wine, balsamic vinegar, Worcester sauce and (if you're using it) Tabasco.

Stir well, bring to the boil then turn down the heat to simmer with the lid on for at least an hour, ideally two or more.

Keep checking intermittently and stirring. Leave the lid off for a while if the sauce is too liquid.

It's a pan of pasta sauce
What more do you want?

This recipe makes plenty for four adults.
Serve with pasta (well, duh!) and bread

NOTES
As a pasta sauce this needs to be nice and smooth, so the onions, carrot and celery need to be finely chopped. Also, make sure the mince is nicely broken up when frying it. The mushrooms add a bit of texture so need to be chopped larger. It's actually a good way to hide vegetables if you have a sprog with an aversion to culinary plant matter.

Using pasata instead of a tin of tomatoes makes a more smooth, almost creamy texture. Tinned tomatoes are cheaper though

Tabasco adds a bit of subtle piquancy so don't use too much. It's not supposed to be "spicy". On the other hand, my piquant might leave some chilli-dodgers with steam blowing out of their ears. These things are relative so leave it out if you or your guest(s) are effete.

Pasta for this is traditionally spaghetti, but in the Sweary household we tend to use something that takes less cutlery skill to eat, like penne or fusilli, mainly because Mrs Sweary can't eat spaghetti without looking like an extra from True Blood when she's finished (see picture for an idea of what I mean).

Darling, but you've got a wee bit of sauce round your mouth.
I told you you should have ordered penne for your bolognaise instead of spaghetti

Pasta Arrabiata

There are few dishes that are truly as easy to make, as cheap or as utterly fucking delicious as this little gem. You could buy a jar of factory-made pasta sauce, but you'd be frigging stupid when this will take probably just as long and tastes infinitely better. It's really like the difference between Corn Flakes from Kellogg's and corn flakes from a chiropodist.

In our house we call this recipe "bacony thing" for some historic reason we can't remember. It is probably the stupidest name for a meal there has ever been, but it's ours. This is especially the case because, in many restaurants, arrabiata is made as just a spicy tomato sauce without the bacon (or in some cases the bacon is replaced by salami or even chorizo). There would be other differences between "bacony thing" and "arrabiata" on a menu, most obviously about ten quid a fucking portion as a second language supplement, because anything in a foreign language costs more.

Naming issues aside, I started making this many years ago when I was a student. A wanky, pretentious student with a foul mouth so, obviously, I've changed in the intervening time: I'm no longer a student. Yet, I still come back to this fantastic dish. It's a family staple which we have every week. It's usually the first thing we make when we have our first dinner after coming back from holiday. I got the idea of this from a recipe book I purloined from my Dad before I went to university. That recipe is called penne arrabiata, meaning angry (pasta) quills.

Funnily enough, in Italian, spelling penne with one fewer "n" apparently means penis. Pene arrabiata is therefore "angry penis". This makes me think of Noel Edmonds getting upset and stamping on the pavement after receiving a parking ticket. Why is he called "Noel"? Because there's no "L" in "smug, hideous shirt-wearing, bearded prick"

INGREDIENTS
2 tbsp olive oil
1 medium onion, finely chopped
4 cloves garlic, crushed (or more, you can't put too much garlic in this dish)
220g smoked bacon, finely chopped (an odd quantity, I admit, but that's how they package it)
1 medium red pepper, finely chopped
1 tin tomatoes
1 tbsp tomato puree
Black pepper
1 red chilli, finely chopped
1/2 tsp mixed herbs (dried work, but fresh are better if they are available)
1 bay leaf
2 tsp balsamic vinegar

Arrabiata Ingredients
The bacon, finely chopped along with the fresh vegetables. Note the fresh thyme on the plate

RECIPE
Pour the oil in a pan and heat before adding the onion and garlic. Fry for 5 minutes until translucent then add the bacon and continue to fry until that's cooked. Throw in the pepper and fry for another minute or so. Pour in the tomatoes, add the puree and stir well. Grind in plenty of black pepper, add the chilli, the herbs and bay leaf then pour in the balsamic vinegar and stir well. Cover and simmer on a low heat for 30-60 minutes. You may need to reduce the liquid in the pan if it's especially runny.
How it looks when it's finished
Note bay leaf

 Serve it over pasta with bread on the side to mop up the sauce

NOTES
The recipe I developed this from didn't have red pepper in it but it bulks out the dish and works well. It needs to be fairly finely chopped like the other ingredients to make a smoother pasta sauce.

As I mentioned above, this recipe can be made without bacon for an even cheaper, vegetarian/vegan version which is still better than some ready-made crap you can buy in a jar.

Unlike most of my previous entries, whilst containing chilli, it's only there to add a slight kick. It does need shitloads of garlic though. It can't really have too much garlic.

While the original recipe was penne, virtually any type of pasta would do: spaghetti, fusilli,even tagliatelli. You'd probably be best drawing the line at tinned ravioli, mind.

Lamb Tagine


Eat tagine and you too could look like this.
Morocco Mole, popular sidekick of Secret Squirrel and also the first indication you've got malignant melanoma after spending too long in the sun in Marrakech

You can't do any recipe of North Africa or the Eastern Mediterranean without mentioning the name of arguably the most trendy cook of the moment, Yotam Ottolenghi. He has a reputation for delicious food which is simple and rustic. However, he also has a tendency to use authentic ingredients in his recipes which, although they may be common in a souk in Tripoli, are not so easy to come by in the UK outside of a few small, wanky, over-priced delis in Notting Hill. For example, you have more likelihood finding a 70s male celebrity without a sex-pest-shaped skeleton in his closet than finding freeze-dried organic gerbil spleens down your local Co-Op. Anyway, I've mentioned him now, so onto my own recipe for lamb tagine.

A tagine is the name of the cooking pot which is essentially a glorified casserole dish with a lid shaped like a slightly squashed witch's hat. The dishes that take their name from the pot are usually mildly spiced stews that are cooked long and slow. This is actually doing an entire cuisine a huge disservice since, if cooked well, Moroccan food is fucking fantastic.

As well as being famous for its subtle, aromatic, spicy flavours, Moroccan food also uses a lot of dried fruit. Now, forgive me for riding rough-shod over centuries of culinary culture, but I largely think that dried fruit has as much place in a savoury dish as Clostridium botulinum. This goes doubly for dried apricots which, though commonly used in Morrocan tagines, are the dessicated haemorrhoids excised from the infernal arseholes of the devil's own herd of Apocalyptic wombats, in my opinion. I mean, if you want to add fruit, why not go the whole hog and stick in a packet of Fruit Pastels while you're at it and maybe serve it up with custard?

Anyway, the upshot of this preamble of dissing the Yot and admitting how much I despise dried fruit in main courses means this recipe is about as authentically Moroccan as a fez made from polyvinylchloride in Taiwan and purchased on Blackpool seafront. You want authenticity, piss off to Agadir and eat there. Meanwhile, this recipe tastes fucking great and it's well worth the time and effort to make it.

INGREDIENTS
2tbsp olive oil
500g cubed lamb
1 medium onion, sliced
2 cloves garlic
100g mushrooms sliced
2 preserved lemons,
150g fresh tomatoes, peeled then halved
2tsp paprika
1 tbsp cumin
10cm cinnamon stick
1 bay leaf
1 tsp ginger
1 tsp ground black pepper
1 fresh red chilli, finely chopped
pinch of saffron
vegetable stock cube
500ml water
1 red pepper chopped into sticks
1 courgette cut into sticks

Spice: the final frontier

RECIPE
Heat the olive oil in a hob- and oven-proof casserole dish and fry the meat to seal it. Remove it with a slotted spoon and add the onions to remaining oil to soften. Add the spices and garlic for about a minute, mixing to make sure they don't stick to the dish. Throw in the mushrooms and fry for another couple of minutes.

Add a little of the water to a cup and mix up the stock cube.

For the preserved lemons, cut them in two and scoop out the middle with a spoon. Discard the flesh and finely chop the skins.

Return the lamb to the dish and add the preserved lemons, tomatoes, water and the stock cube mix. Bring to the boil, mix well then layer the pepper and courgette on top of the rest of the stew. This means that the vegetables steam rather than boil and totally disintegrate over the long, slow cook.

Cover and put into the oven at 145°C for 2-3 hours



Tagine ready to go in the oven
Note the vegetables layered on the stew. Also note this is a Pyrex casserole dish and not an actual tagine pot. I'm not that much of a foodie wanker

This serves two people easily. Dish it up with rice, bread or couscous, like the recipe I'm writing next  for orange couscous.


NOTES
Preserved lemons are available from supermarkets. They are not the same as fresh lemons. They look like this:



You could put any combination of vegetables in this. Well, OK, not any combination. Lettuce would be a mistake, for example and cabbage would be a bad idea (cabbage is actually generally a bad idea in any situation, to be fair). However, carrots work well, as does aubergine, green beans or squash.

In best Rick Stein style, I could twat on about how I tasted something like this recipe, as cooked over a bottled gas stove in individual pots, in some street-side cafe in Marrakech a few years back. A place which had a spice shop round the back where I bought a large bag of saffron at a really good price, but that's really not the fucking point of this blog, is it?

Courgette in tomato

What can you say about courgettes? They're green and phallic, like a verdant winky, disembodied from its Martian owner in some horrendous intergalactic Bobbit incident. They're small marrows with a French name, except in the USA and Italy where they call them zucchinis. They are also quite tasty.



After an opening salvo of dishes which are New World, in-your-face, chilli-laced and full of dead animals to start the blog, this is a simple, fresh, vegetarian dish that works as a side dish as one of the two veg of a Sunday roast dinner or on its own as a pasta sauce. It's the sort of recipe that Rick Stein would twat on about in a flowery manner, relating how he had seen it made from vegetables fresh from Monet's garden by some elderly matriarch in Provence one year when he was a student. It's at  that stage in his programme when you're screaming at the telly "Just shut up and cook the fucking recipe, you pretentious prick!". I got my courgettes from Sainsbury's.

INGREDIENTS
1 medium courgette: topped, tailed and sliced
Half a red onion, finely choppped
Two cloves of garlic, crushed
Half a tin of tomatoes
1 tbsp tomato puree
2 tbsp or more olive oil*
Pinch of Salt
Black pepper
Small bunch of fresh oregano, finely chopped (or a pinch of dried)

RECIPE
Pour the oil in a pan and heat. Fry (or sautee if you're of the foody wanker persuasion) the onion and garlic until the onion is transparent, about a couple of minutes.

Throw in the courgette and fry for another 10 minutes until they start to get tender.

Add the tomatoes, tomato puree, oregano and salt and pepper.

Let it stew for 30 minutes or so, until the courgettes are cooked, and serve.

NOTES
You could pep up the dish by adding a splash of lemon juice but taste before serving as it might need some sugar to offset the tartness. Also, like any dish, this would be improved by a good slug of white wine.

Herbs
Oregano goes well with tomato, but you could use thyme. 

*This is what Nigel Slater might call "a glug". Now, I'm not aware in which system of mensuration (no, not that)  the "glug" is a unit. Presumably it's from the same descriptive system as "a tit of milk", "a turd of mashed potato" and "a fart of lettuce". Whatever, it's definitely not an SI unit. This is in contrast to the "slug", as mentioned for wine above, which is (SI standing for "Sweary Implementation" in this case).
