A gosling - or “green goose” as it used to be called in Britain - is a tender young bird, not more than six months old, with fine pink flesh and creamy skin. At their best from July to the end of August, goslings are very delicate in flavour.
A goose is an adult bird six months to one year old. The legs should be yellow and pliable, and the webbing of the feet easily torn. The bill should be yellow with few bristles and the underbill easily broken when bent. The breast should be plump, but without too much fat, and the skin smooth. A goose should not be eaten after it is a year old as the flesh becomes tough.
