I've seen 'home smoking' being demonstrated on tv a couple of times, using either a wok or a roasting pan. We've got an old wok in need of replacing so I thought I'd give it a go using some salmon.

You'll need a wok with a lid and a rack which fits in the wok to stand the salmon on. Start by lining the bottom of the wok with foil, using enough to stick about an inch or so above the lip of the wok because it needs folding over the lid to reduce the amount of smoke which escapes.

Mix together a couple of tablespoons each of rice, sugar, tea leaves. Pour into the foil. Place a rack above this mixture - I didn't have a suitable rack so I used a thick foil 'pie dish' (the sort which is supposed to be disposable) which I cut holes in.

Place the wok over a medium heat. When the mixture starts smoking, put the lid on and fold the foil over the lid. Turn the heat down to low. After about 15 minutes, check the salmon and give it a few more minutes if needed.

It may be a good idea to open the kitchen window and close the door before doing any of this - the smell of smoke managed to fill the house. The salmon came out looking more like 'smoke damaged' than smoked but it tasted good. The technique would work with other fish but it was a lot of hard work.
