HOW TO MAKE A SAUCE THICKER WHEN IT IS TOO THIN, AND THINNER WHEN TOO THICK.
Take two fresh eggs, break them gently, and separate the white part from the yolk; be careful to have the yolk free from any white (there is in every yolk a little white spot, which you cannot detach without using a fork, knife, or spoon); mix well the two yolks with two or three tablespoonfuls of the sauce that is too thin, and a piece of butter the size of a pigeon's egg; then take the sauce from the fire, pour the mixture in it, little by little, stirring all the time; when the whole is in, put back on the fire for three or four minutes, but do not allow it to boil; take away and use. When too thick, add broth.
Allemande.—Chop fine and fry in butter four or five mushrooms; then add a little flour, and four or five tablespoonfuls of broth; reduce it to a sauce; put a piece of butter the size of an egg in it, also a sprig of white parsley chopped fine, one of thyme, a clove, a bay-leaf, a clove of garlic, a little nutmeg grated fine, the juice of a quarter of a lemon, and three well-beaten yolks of eggs, boil two or three minutes, and use. If found too thick, add a little broth.
Anchovy Butter.—Strain essence of anchovy through a fine sieve, and knead it with fresh butter, or salt butter that you have kneaded in cold water previously, and it is ready for use.
Anchovy Sauce.—Use butter without salt; if salty, work it in cold water. Set three ounces of butter in a saucepan on the fire, and melt it slowly; then add about two teaspoonfuls of essence of anchovy; stir a few seconds, and it is done. More anchovy may be used if liked. It is served in a boat.
Apple.—Peel, quarter, and core four or six apples, and set them on the fire in a small saucepan, with two tablespoonfuls of water; stir now and then till done; when done, mash through a fine colander; add a little sugar, and it is ready for use.
If found too thin, keep on the fire for some time. If too thick, add a little water.
Cranberry.—Put a quart of cranberries in a saucepan and set it on a rather slow fire; stir occasionally till done; mash gently through a fine colander, or through a strainer; add a little sugar, and use.
Currant.—Proceed as for a cranberry-sauce in every particular, except that it must be mashed through a strainer or through a towel.
Peach.—Stone about a quart of peaches, and proceed as for apple-sauce for the rest.
