Roast Poblano crema

I live about ten miles from Ely, where there is a cathedral, a very, very good bookshop, and an excellent twice-monthly farmers' market. There are about 30 stalls, and it's a great place to pick up local meats (a slab of belly pork is lurking deliciously in the freezer as we speak) and things like good free-range eggs, pork pies and ostrich products from Bisbrook farm. Because this area is right at the heart of East Anglia's patchwork of farms, the stalls are packed to the gills with interesting fruit and vegetables. The bread in particular tends to run out early - if you do visit Ely for the market, try to get there before 11am.

Edible Ornamentals, a Bedfordshire farm growing chillies, usually has a stall full of chilli plants, pots of sauce and chillies both fresh and dried. I love their chilli sauces (some so hot it's amazing that a glass jar can contain them without dissolving in protest), but their fresh chillies can be downright amazing, and I was delighted to score five big, fresh Poblanos for £3.

Poblanos are the fresh pepper which, when dried, become Ancho and Mulato chillies. (An Ancho is dried more than the slightly soft and fruity Mulato.) They are a mild, purple pepper with a deep, fruity background - lots of flavour and very little heat, although the redder pepper in my bag was a little hotter than the others. I was planning a chilli con carne, and had some Mulatos in the cupboard ready for deployment in that. What better to eat as a side dish than a Poblano crema - those fresh Poblanos roasted, skinned and mixed with crème fraîche, lime and coriander?

To make enough crema to accompany a chilli for two or three, you'll need:

5 fresh Poblano peppers
5 tablespoons crème fraîche (or Mexican crema, if you can find it)
6 spring onions (scallions), chopped
1 large handful chopped coriander
Juice of 1 lime
Salt and pepper
Olive oil

Rub the whole peppers with olive oil and arrange in a baking tray. Cook at 180° C (350° F) for 20 minutes, until the skin is browned and blistering (see picture). Put the whole cooked peppers in a plastic freezer bag, seal the top and put aside for five minutes while you chop the spring onions.

The business with the freezer bag will help the peppers steam from the inside, loosening the skin so you can peel it off easily. When the peppers are cool enough to handle, peel off their skins and discard, then chop open and carefully remove all the seeds. Some people like to do this under a running tap, but I recommend keeping the cooked peppers well away from water to preserve their delicious juices. Slice the silky peeled peppers into long, thin strips and put in a bowl with any juices. (I really enjoy this bit - peeled, roast peppers feel beautiful between the fingers.) Reserve a few strips on a plate to use as a garnish.

Stir the crème fraîche, pepper strips, spring onion and coriander together with the lime juice. Taste, and add salt and pepper. Garnish with more coriander and the reserved peppers, and chill for an hour before serving.

This is deliciously cooling served alongside a chilli con carne - it also makes a fantastic filling for baked potatoes and is gorgeous slopped on a baguette.

Mexican squash and corn cream

Do try this one - it's seriously good and has worked its way up to being a frequent star alongside my roast dinners. This silky, sweet puree works unbelievably well as an accompaniment, especially with poultry - I hope some of you will try it with your Christmas turkey. It's rich and packed with flavour; and like many recipes which utilise creamed corn, it's a favourite with children. It also works as a great quick main dish (and is lovely if you're entertaining vegetarians - try it over rice with an interesting salad).

Butternut squash originates in Mexico, and it has an affinity for other Mexican ingredients like the corn, the coriander and the chillies. I've used crème fraîche here to loosen the mixture - an authentic Mexican dish might use crema, the thick, Mexican, sour cream, but really the difference between the two products is minuscule. If you can't find smoky ground chipotle chillies where you are, just substitute your favourite crushed, dried chillies or chilli powder.

To serve two as a main dish or about four (depending on greed) as a side dish, you'll need:

1 butternut squash
1 can creamed corn
3 heaped tablespoons crème fraîche
1 tablespoon salted butter
1 teaspoon salt
1 teaspoon freshly ground black pepper
¾ teaspoon ground chipotle chilli
1 large handful roughly chopped coriander

Peel the squash (you'll find a serrated knife the best tool for this job - that peel is tough), remove the seeds and stringy pith, and chop the flesh into pieces about an inch square. Cover with water and simmer for 15 minutes until the pieces of squash are tender and soft when poked with a knife.

Drain the water off and return the squash pieces to the pan. Add the corn, butter and crème fraîche to the pan and mash with a potato masher off the heat until smooth. Season with the salt, pepper and chillies - you'll find this dish will require quite a lot of salt for maximum flavour because of the natural sweetness of the vegetables.

Return the pan to a low heat and bring to a gentle simmer. Remove from the heat again and stir in the coarsely chopped coriander. Serve immediately.

This squash and corn cream freezes well.

Carnitas

Carnitas are one of my favourite Mexican dishes. This is a luscious way with pork, which brings out a deep flavour from the meat and gives it a superbly silky texture. Unfortunately, I can predict as I type this that some of you are going to balk once you've read the recipe - because all this deliciousness comes about because the meat is poached in nearly its own weight in pork fat, then drained. I know that the word 'lard' is about as popular as the word 'anthrax' in recipes these days. It's a great, great shame - there is joy in good foods, and some of the very best are thick and unctuous with glossy animal fats.

We appear to have developed a terrible national neurosis about fat in general, and animal fats in particular. In moderation (after all, you're probably not going to be eating carnitas more than a couple of times a year at the most), fat is just part of a balanced diet. It provides a vehicle for vitamins A, D, E and K, which are only made available to your body when dissolved in fat. Fat maximises flavour, creates exceptional textures (think of a lardy puff-pastry, a potato cooked in goose fat, a crisp slice of bacon), and, quite simply, fat can make you happy, which is as positive an outcome as I can imagine. Fat is, undoubtedly, fattening...but I encourage you to take a trip to the supermarket and look at the average size of the glum people stuffing their trolleys with low-fat spreads and low-fat ready meals. Worst of all, there have been reports recently that parents have been so worried by the dire messages we're all getting about fat that they are feeding their children a diet unnaturally low in fats, resulting in deficiencies in those fat-soluble vitamins and, surprisingly, obesity later in life. If you're worried about your cholesterol level, the best advice I can offer is to follow your carnitas up with a bowl of porridge for pudding.

So here is an unapologetically fatty recipe. Please cook it and enjoy it rather than worrying about it. To serve six, you'll need:

1 kg lean pork, cut into 2-inch cubes
750g lard (this is best purchased from your butcher if he cooks on the premises - otherwise, a block from the supermarket will be fine)
1 onion
1 handful coriander
2 green chillies
Sour cream or crème fraîche, salsa and tortillas to serve.

Make sure the pork is well trimmed of fat. I bought a whole, boned leg joint and diced it myself, removing the skin - this can sometimes be cheaper than buying ready-diced pork. Put the pork in a large bowl and season it generously (use a little more salt than you think you will need) with salt and pepper.

Melt the lard over a medium flame in a large, heavy-bottomed pan. Tip the pork into the lard and simmer for between 1 hour 15 minutes to 1 hour 30 minutes. When the pork is ready it will just be beginning to brown, and it will be soft to the fork. Use a slotted spoon to remove the pork from the lard, and put it in a baking dish. Preheat the oven to 200° C (400° F).

Use two forks to shred the meat well. Chop the onion into small dice, and slice the chillies. Chop the coriander finely. Mix the onion, chillies and coriander with the meat in the dish, then cover the whole lot tightly with tin foil.

Bake the dish for 15 minutes. The carnitas will be warmed through - the onion, not completely cooked, will be sweet, but will still retain its crunch. I poured some heated mole verde from Sol at Mexgrocer over the dish, but this isn't necessary - I just felt like some delicious Mexican overkill.

Serve your carnitas with some salsas, soured cream and tortillas, (and watch this space for a pathetically easy guacamole). Summer might have finished, but if you eat like this you can almost convince yourself that your dining table is temporarily in Mexico.
