Confit is a traditional French way of cooking duck. The method is centuries-old - first the meat is cured in salt, then poached in its own fat. Be prepared that this special recipe does take a while, but it's definitely worth it. You'll need about 1 litre (1¾ pints) of duck fat, available from your butcher or larger supermarkets. If you don't have enough, combine with peanut oil or chicken fat, or just use either of those instead.
