Black Butter to serve round Broiled Haddocks. (Mrs. Thomas.)
To a teacupful of strong cold first stock add ½ oz. or ¾ oz., no
more of butter, and melt both, stirring well, in a stewpan, add
1 tablespoonful of mushroom catsup, the same of Harvey’s sauce,
also ½ spoonful of Worcestershire sauce, and let all boil up
together. Serve in a sauce-boat. Another copy says, “Serve
round the fish, not over it.”
