Collops, to mince.
Chop some beef as fine as possible; the under part of roasted beef without any fat is best. Put some onions, pepper, and salt to it. Then put a little butter in the frying-pan; when it is melted, put in the meat, and stew it well. Add a cupful of gravy; if you have none, water will do. Just before it is done put in a little vinegar.
