This recipe is zeus as far as tofu goes - fresh, elegant, luxurious and perfectly balanced, like an italian suit. It's also one of the simplest tofu recipes I know (notwithstanding zhao's one upthread) and is one of the few that works with what flavour the tofu naturally has rather than trying to make it taste of something else by deep frying it and bashing it with spices. It's all about the balance and subtlety so the recipe is maybe a bit less flexible than most:
1 fairly mild fresh chilli
1/2 sweet red pepper
1/4 tsp salt
2 tbs vegetable oil
1 tsp cornflour
1/2 lb tofu, as firm and dry as you can get (I use the Cauldron stuff)
1tbs dark soy
2 floz water
4tbs finely chopped fresh coriander
Mix the cornflour, soy and water in a glass
Slice the peppers into short fine shreds
dice the tofu
Heat the oil in a pan. Stir fry the peppers and salt for about 30 seconds, then chuck in the tofu. Turn the heat down and push the tofu around til it's hot. Add the soy / cornflour mix and stir until it thickens. Add the coriander, stir a couple more times and serve with rice / noodles and a big fucking slab of beef.
