Kidneys in Sherry

• 2 tablespoons butter or good oil
• 1 sweet onion, minced
• 1 pair veal kid

Wash kidneys and cut into little pieces. Brown the onion in the fat and add the meat. Add seasoning (salt, pepper, fresh-chopped parsley or basil or whatever herb you like). Add the sherry and simmer five minutes. Serve very hot, with the watercress as a garnish.
