Dutch Sauce.—This is very similar to Allemande Sauce. Take half a pint of good butter sauce, make it thoroughly hot, add two yolks of eggs, taking care that they do not curdle, a little pepper and salt, a suspicion of nutmeg, and about a tablespoonful of tarragon vinegar. Some persons instead of using tarragon vinegar add a little lemon juice, say the half of a fresh lemon to this quantity, and half a dozen fresh tarragon leaves, blanched—that is, dipped for a few seconds in boiling water—and then chopped very fine. The tarragon vinegar is much the simplest, as it is very difficult to get fresh tarragon leaves unless one has a good garden or lives near Covent Garden Market.

Dutch Sauce (Green).—Proceed exactly as above and colour the sauce a bright green with a little spinach extract (vegetable colouring, sold in bottles by all grocers).

Egg Sauce.—Take half a dozen eggs, put them in a saucepan with sufficient cold water to cover them. Put them on the fire and let them boil for ten minutes after the water boils. Take them out and put them into cold water and let them stand for ten minutes, when the shells can be removed; then cut up the six hard-boiled eggs into little pieces, add sufficient butter sauce to moisten them, make the whole hot, and serve.

N.B.—Inexperienced cooks often think that hard-boiled eggs are bad when they are not, owing to their often having a tinge of green colour round the outside of the yolk and to their emitting a peculiar smell when the shells are first removed while hot All eggs contain a small quantity of sulphuretted hydrogen.

Fennel Sauce.—Blanch and chop up sufficient fennel to colour half a pint of butter sauce a bright green, add a little pepper, salt, and lemon juice, and serve.

German Sweet Sauce.—Take a quarter of a pound of dried cherries, a small saltspoonful of powdered cinnamon, and a few strips of lemon peel, and put them in a small saucepan with about a quarter of a pint of water, or still better, claret, if wine is allowed, and let them simmer on the fire gently for about half an hour; then rub the cherries through a wire sieve with the liquor—(of course, the lemon peel and cloves will not rub through)—and add this to a quarter of a pound of stewed prunes. This is a very popular sauce abroad.
