Melt one-fourth cup butter, add one tablespoon finely chopped onion, a stalk of celery, two slices carrot cut in pieces, and two tablespoons finely chopped lean raw ham. Cook until butter is brown, then add one-fourth cup flour, and when well browned add two cups Consommé, bit of bay leaf, sprig of parsley, blade of mace, two cloves, one-half teaspoon salt, and one-eighth teaspoon pepper; cook five minutes. Strain, add duck, and when reheated add sherry wine, stoned olives, and mushrooms cut in quarters. Arrange on dish for serving, and garnish with olives and mushrooms.
