How much meat to order

Here is a general guide  - based on average portions. 

Ham, raw. Order 8 oz (225 g) per portion. This will give you 4 oz (110 g) of cooked ham per portion. Ham loses approximately 1/3 to 1/2 its weight in the boiling process, so if you need 2 kg of cooked meat, you should order 4 kg of raw ham.

Meat on the bone (e.g. Rib Roast) - allow 1 lb (450 g) per portion.

Meat, boned (e.g. Rump roast/Topside Roast/Boned Pork Loin) - allow 8 ounces (225 g) per portion.

Meat boned for casserole (e.g. venison casserole pieces) allow 4 oz (110 g) for a casserole with equal vegetable ingredients e.g. mushrooms, onions, carrots. If the casserole meat is just poached in wine without any additional vegetables allow 8 oz (225 g) per portion.
