Wild ducks (such as mallard, teal and black duck) have a stronger, slightly oilier taste. They can range in size from less than 500 g to 5 kg but most are smaller than domesticated birds.
The mallard is the largest and should be basted while cooking as it can become dry. Black ducks are slightly smaller with dark, oily meat and each will serve one to two people. A teal is a tiny, nice-eating duck and serves only one person. Ordinary duck recipes can be used for wild ducks, but you will have to adjust the cooking times and temperatures as wild duck should be cooked rare. It is best roasted whole, at a high temperature of 200 degrees C. The bird should be roasted resting on each leg alternately, then on its back to ensure even cooking.
For a small duck such as teal, allow 12-20 minutes for the whole bird, depending on its size. For a larger mallard, allow 20-30 minutes for the whole bird. Do not prick a wild duck all over before roasting it, as they are leaner than domesticated ducks.
