Casserole recipes: mutton with fermented bean curd, and chicken and chestnut
Casseroles are good at keeping the chill at bay. Here are two easy-to-make winter warmers

Cold-weather Chinese cooking means fewer light steamed dishes and more braised food with rich sauces. For the following recipes, use Chinese sand pots, which are inexpensive and come in many sizes. The vendor will (or should) have a bucket of water near the pots - submerge the one you're thinking of buying to see if it has any fissures; if it does have a crack, small bubbles will form on it. If you don't have a sand pot, use an enamelled cast-iron pot.

This is one of my favourite winter dishes. It's easy to make but the flavours are deep and complex. If you can't find mutton, which has a gamier flavour, choose lamb that's on the bone, preferably with some tendon, which will give the sauce a deliciously sticky quality.
