Take enough of the brioche sponge to fill a good-sized mold two-thirds full. Work into this 1/2 cupful of raisins cut into small pieces, 1/4 cupful of candied cherries, 1/2 cupful of chopped nuts, and 1/4 cupful of coconut.
Place in a mold and allow it to rise until the mold is nearly full. Bake from 45 minutes to 1 hour, turn out of the mold, and allow to become cold. Cut into thick slices with a knife that has been heated in the flame, and serve with apricot or pineapple sauce.
