Fresh free-range geese are available direct from the farmgate or from a high class butcher or poulterer, and from food halls and supermarkets. They are also sold increasingly through mail order and the internet.
Fresh geese can be bought from Michaelmas in late September to December. They should be ordered well in advance for Christmas.
Geese are sold oven-ready, which includes the weight of the giblets. Oven-ready weights range from 4.3kg/9.5lb to 6.35kg/14lb and long-legged from 5.40kg/12lb to 9kg/20lb. Allow approximately 1lb-1.5lb per person.
At home remove the giblets and store them, and the goose, separately in the refrigerator. Check the weight of the giblets and fat before stuffing the goose. This will give the correct weight and you can work out how much cooking time is needed.
