A glamorous French chef called Alexis Soyer was an unlikely hero of the Crimean War. He heard the PBI were suffering from appalling conditions in the front line. Cold and dysentery were killing more men than shot and shell.
Soyer designed a simple but brilliant stove that could use any fuel and cook any food. He also created recipes for cooking hearty food on a massive scale using his eponymous stove.
Here's Soyer's recipe for a huge stew to feed 100 men:
Food for 100 men, using two stoves
Cut or chop 50Lbs. of fresh beef in pieces of about 1/4Lb. each; put in the boiler, with 10 tablespoonfuls of salt, two tablespoonfuls of pepper, four tablespoonfuls of sugar, onions 7 Lbs. cut in slices: light the fire now, and then stir the meat with a spatula, let it stew from 20 to 30 minutes, or till it forms a thick gravy, then add a pound and a half of flour; mix well together, put in the boiler 18 quarts of water, stir well for a minute or two, regulate the stove to a moderate heat, and let simmer for about two hours. Mutton, pork, or veal can be stewed in a similar manner, but will take half an hour less cooking.
Note. A pound of rice may be added with great advantage, ditto plain dumplings, ditto potatoes, as well as mixed vegetables. For a regiment of 1,000 men use 20 stoves.
