Crab Sauce.

Make the drawn butter as usual, and stir in the milk. Pick the meat from the crab, chop very fine, season with cayenne, mace, and salt to taste; stir into the drawn butter. Simmer three minutes, but do not boil.

Lobster sauce is very nice made as above, with the addition of a teaspoonful of made mustard and the juice of half a lemon. This is a good fish sauce.
