(Recipe #34, page 133)
Use a sharp knife to shave the scales very close to the skin, leaving it white; split the fish and cut it into pieces of a convenient size, rinse them well, boil them for 5 minutes in salted water, and place them in another kettle.
Meanwhile boil capers in white wine and some of the fish broth, with lemon juice and peel, a generous knob of fresh butter, and some grated white bread. Pour this sauce over the pickerel and let the fish stew in it gently for ¼ hour. If desired, when the fish are served the sauce can be slightly seasoned with anchovies. Then stir in an egg yolk and bring the pickerel hot to the table.
