Boiled Mutton.
The best part for boiling is the leg. Put on in boiling water and cook, allowing fifteen minutes to the pound. Make a sauce by taking out a cupful of liquor when it is nearly done, cooling it until you can take off the fat, then heating again in a saucepan and stirring into it one tablespoonful of butter, two teaspoonfuls of flour, wet up with cold water. Stir for five minutes, putting in a teaspoonful of chopped parsley, and after another boil, take from the fire before you put in the juice of a lemon.
In this, as in other cases where the liquor in which meat is boiled is to be used for broth, salt slightly while cooking, sprinkling all over lightly with salt the moment you take it from the fire. Serve the sauce in a boat.
