93. BEURRE NOIR, OR BLACK BUTTER SHARP SAUCE.
PLACE about six ounces of good fresh butter in a small stewpan, put it on the fire to melt, and then allow it to fritter, so as to acquire a light-brown colour; then take it off the stove, skim it, and quickly pass it through a sieve, into a stewpan containing four tablespoonfuls of French vinegar, a dessert-spoonful of chopped capers, ditto Harvey sauce, ditto mushroom-catsup, and a piece of glaze the size of a walnut, and sufficient pepper and salt to season the sauce; boil the whole well together, and use it for boiled skate or broiled mackerel. With whatever kind of fish this sauce is served, fried parsley forms an indispensable adjunct.
