Lobster scalloped in shells

Two cupfuls of lobster meat, cut into small dice. One cupful of white stock, and the same of unskimmed milk. Two tablespoonfuls of butter made into a white roux with one tablespoonful of flour. Salt and paprika to taste. Minced parsley and juice of half a lemon. Beaten yolks of two eggs. Halves of two lobster shells, cleaned. Pinch of soda in milk.

Stir the hot stock and the scalded milk into the roux, season, boil once; remove from the fire, add the eggs and lobster dice and fill the shells. Cover with fine crumbs, rounded, dot with butter, sprinkle with cayenne and bake to a delicate brown.
