Scrape, pound, and pass through a sieve the white fish. Put the pulp in a bowl, season with salt, pepper and cayenne; whip into it the whites, and add slowly, beating all the time, the cream. Poach a small piece to see if right: if too thick add more cream, if too thin add more white of egg. A pretty decoration for fish timbale, especially when made of salmon, is lobster coral, dried and pounded to powder, and sprinkled on the buttered mold. Fish timbale is usually made in a solid piece and served as a fish course. With white fish serve a tomato sauce; with salmon a Poulette or a cream sauce, or Mayonnaise.
