Shrimp sauce for baked bass
Strain the gravy left in the pan, and stir in a brown roux made by heating a great spoonful of butter in a frying-pan and working in a tablespoonful of browned flour. Add four tablespoonfuls of boiling water to gravy and roux, or enough to bring it to the consistency of cream, then the juice of half a lemon, cayenne or paprika to taste; lastly, half a can of shrimps, chopped fine. Boil one minute, pour some over the fish, the rest into a gravy-boat.
