Dutch Sauce for Meat or Fish.
Put two or three table-spoonfuls of water, as many of vinegar, and as many of broth, into a saucepan, with a piece of butter; thicken it with the yolks of two eggs. If for fish, add four anchovies; if not, leave them out. Squeeze into it the juice of a lemon, and strain it through a sieve.
