Slice an onion and fry it in butter till it is brown; add pieces of pork and of mutton freed from fat and skin; cover them with water and throw into it any kinds of vegetables that you may have; but particularly sliced carrots and turnips and green cabbages; put it in the oven to cook. In another saucepan boil some white haricot beans, salt, and pepper, until they are tender, when they must be added to the stew with a small quantity of the liquor that they have been boiled in.
