Roast buttered chestnuts

Roast chestnuts – another truly seasonal ingredient. When I was a kid, they were a real treat. We bought them in paper twists from the man with a roasting cart outside the British Museum, we gathered them in the woods to roast them in the oven at home, and once, excitingly, we roasted them on a coal shovel in the fireplace, one chestnut left unpricked so it exploded like a violent kitchen timer to tell us when it was ready.

Now, chestnuts just roasted in their skins and eaten immediately are delicious. But an Italian friend at university taught me to sauté the peeled chestnuts in butter and sprinkle them with coarse salt after roasting, and it’s now far and away my favourite way to prepare them. The butter kicks up the flavour a notch, the sautéing does wonderful things to the chestnuts’ texture, and a scattering of coarse salt (I used a French fleur de sel) is the perfect contrast to the sweet, fluffy flesh of the chestnuts.

If you’re stuck in the UK, you’re likely to be stuck with the English chestnut, which has a papery pith inside the shell, covering the nut. It’s a pest to remove, and is easiest to take off while the chestnuts are still very hot – this is easiest to deal with if you are one of the asbestos fingered fraternity. It’s great if you can find someone to help you peel – it gets the job done faster, so you can get to the chestnuts when the piths will still come away easily.

The Chinese chestnut, a little smaller than the English variety, has no inner pith, and we ate them by the bushel-load when I was a kid in Malaysia. They’re a lovely chestnut – if you can find some where you are, grab plenty and freeze some – all raw chestnuts freeze well. In the USA this pithless Asian variety has been hybridised with the sugary American variety, so you can buy big, fat, achingly sweet chestnuts without any papery pith. I hope British growers will cotton on to this trick soon – they’re appallingly good. When you buy your chestnuts, try to find some which are plump and glossy. They lose moisture and flavour quickly, so it’s a good idea to either freeze them until you’re ready to cook them or to cook them as soon as you get them home.

To roast and sauté enough chestnuts (of whatever variety you choose) to serve four, you’ll need:

1kg fresh chestnuts
2 large tablespoons butter
2 teaspoons salt to sprinkle

Preheat the oven to 200°C (400°F). While the oven is warming, cut a cross in the flat side of each chestnut with a sharp knife – try to pierce the skin without cutting into the flesh. This is very important – an unpierced chestnut will explode when it cooks, so make sure you don’t miss any!

Arrange the chestnuts on baking sheets and roast for 25 minutes. Start to peel as soon as you can bear to touch them (this way it will be easier to remove the pith) and set the peeled chestnuts aside.

Melt the butter in a large frying pan and throw the peeled chestnuts in when it starts to bubble. Saute, keeping the nuts on the move, until all the butter is absorbed and any crumbly bits of nut are turning gold and crisp (about 5 minutes). Turn out into bowls and scatter salt over. Serve immediately.

Char siu pastry

Here’s another dim sum recipe; in Cantonese this savoury pastry, a bit like a little pie, is called Char Siu Sau. It’s a parcel of crisp, flaky puff-pastry wrapped around succulent barbecued pork in a sweetly spicy sauce.

Char siu, the barbecued pork in question, has featured on this blog before, and is very easy to make – see the recipe here. The pastry I use to make these is a Malaysian-Chinese flaky pastry, made incredibly short and delicate with a lot of fat and some lemon juice. This is an altogether fatty recipe which is best made for a party (and believe me, if you serve them at a party they’ll vanish in no time at all).

To make about thirty little pastries (they freeze very well before the final baking stage, so you can assemble them and then freeze a few for a treat later on) you’ll need:

Filling
2 fillets of char siu
2 tablespoons lard
8 fat cloves garlic, chopped finely
2 medium onions, cut into small dice
4 tablespoons soft light brown sugar
2 teaspoons sesame oil
2 tablespoons kecap manis (sweet dark soya sauce – use 2 tablespoons of dark soya sauce and a teaspoon of soft light brown sugar if you can’t find any)
2 tablespoons light soya sauce
4 fl oz water
2 tablespoons plain flour
1 tablespoon vegetable oil

Pastry
1 lb flour
4 oz butter
8 oz lard
1 egg, and another to glaze
2 tablespoons sugar
Juice of ½ a lemon
6 fl oz water

Begin by cooking the filling. Chop the two fillets of pork into small dice. Dice the onions finely and chop the garlic. Mix the vegetable oil and flour in a cup. Saute the garlic in the lard until it begins to give up its scent (about 2 minutes) and then add the onions, moving them around the pan until they turn translucent (another 2 minutes or so). Add the sugar, sauces, water and sesame oil to the pan, and bring up to a gentle simmer. Add the diced pork and stir until everything is well coated with the sauce. Add the oil and flour mixture, and stir until everything is thickened (about a minute).

Remove everything to a large bowl and chill in the fridge. (Your little pastry packets will be easier to fill with a thick, cold mixture.)

For really successful pastry, there are a few rules: keep the ingredients as cold as possible, rest the pastry for at least half an hour, and handle it as little as you can manage. To make the pastry, mix a beaten egg with the water, sugar and lemon juice, and chill until nicely cold. Rub the butter, straight from the fridge, into the flour until the mixture resembles breadcrumbs, then use a knife to chop the chilled lard into small dice, about the size of the top joint of a woman’s little finger. Stir the lard into the butter and flour mixture. Add the liquid ingredients to the bowl and use a knife or spatula (cooler than your hands) to bring everything together into a dough. Wrap with cling flim and rest in the fridge for at least half an hour.

When you are ready to assemble the pastries, roll half the ball of dough out into a rectangle about half a centimetre thick, fold it into three (as if you were folding a piece of A4 paper to put in an envelope), turn it through 90 degrees so the long edge is facing you, and roll it out again. Fold, roll and turn another four times. You’ll end up with a slab of pastry which has been folded and rolled into many, many thin, flaky layers (you can see the layers in the raw pastry, already visible partway through rolling, here on the left).

Preheat the oven to 230° C.

Use pastry cutters to make circles, or a knife to make squares, and place a dollop of the cold char siu mixture in the centre of each. Use a beaten egg to seal the edges, crimp with a fork and make a little hole with your fork in the top side of each pastry (important, this – it will allow steam to escape and prevent your pastries from gaping open when they cook). Brush each one with some of that beaten egg, and put on a non-stick baking sheet in the oven for 10 minutes. When the 10 minutes are up, reduce the heat to 200° C and bake for a further 20 minutes. Cool the pastries a little before you eat – the insides will be unbelievably hot, as well as unbelievably delicious.
