1067. The Loss by Roasting (Specific).

The loss per cent, on roasting beef, viz., on sirloins and ribs together is 19-1/6 th; on mutton, viz., legs and shoulders together, 24-4/5 ths, on fore-quarters of lamb, 22-1/3 rd; on ducks, 27-1/5 th; on turkeys, 20-1/2; on geese, 19-1/2; on chickens, 14-3/5 ths. So that it will be seen by comparison with the percentage given of the loss by boiling, that roasting is not so economical; especially when we take into account that the loss of weight by boiling is not actual loss of economic materials, for we then possess the principal ingredients for soups; whereas, after roasting, the fat only remains. The average loss in boiling and and roasting together is 18 per cent. according to Donovan, and 28 per cent. according to Wallace--a difference that may be accounted for by supposing a difference in the fatness of the meat, duration and degree of heat, &c., employed.
