Use six small salmon steaks. Season with salt and pepper. Butter sheets of white paper a little larger than the steaks and lay on each one a thin slice of lean boiled ham. Cook together in butter a chopped onion, a handful of chopped mushrooms, a minced bean of garlic, and a tablespoonful of minced parsley. Spread a thin layer on the ham, lay a slice of salmon upon it, spread with the cooked vegetables, cover with another slice of ham, put another piece of oiled paper over, and fold carefully at the edges. Bake in a moderate oven for fifteen or twenty minutes, and serve in the papers.
