BURNT OR BROWNED BUTTER.
Melt in a frying-pan three ounces of fresh butter, and keep it stirred slowly over a gentle fire until it is of a dark brown colour; then pour to it a couple of tablespoonsful of good hot vinegar, and 110season it with black pepper and a little salt. In France this is a favourite sauce with boiled skate, which is served with plenty of crisped parsley, in addition, strewed over it. It is also often poured over poached eggs there: it is called beurre noir.
Butter, 3 oz.; vinegar, 2 tablespoonsful; pepper; salt.
