Pepper, grated nutmeg, and chopped chives, may be added if liked. Using vinegar instead of lemon-juice makes an inferior sauce.
Mayonnaise.—In warm weather it is necessary to put the bowl on ice while making it. Put one or two yolks of fresh eggs in a bowl with a small pinch of salt; commence stirring with a box-wood spoon, or, what is still better, a stone or marble pestle. Stir without interruption, always in the same way and describing a circle. It is more easily done if the bowl is held steady. After having stirred about half a minute, commence pouring the oil in, drop by drop, and as soon as you see that it is thickening pretty well, add also a few drops of vinegar and same of lemon-juice; then continue with the oil in the same way. Every time that it becomes too thick, add a little vinegar, but continue stirring. You put as much oil as you please; two bottles of oil might be used and it would still be thick. Spread it on chicken salad, etc.
Tartar.—Chop some capers and shallots very fine, mix them well with a mayonnaise when made, and you have a Tartar sauce.
Mushroom.—Proceed exactly as for caper-sauce, using chopped mushrooms instead of capers.
Piquante.—Take a small saucepan and set it on the fire with two ounces of butter in it, and when melted add a small onion chopped; stir, and when nearly fried add a tablespoonful of flour, stir, and when turning rather brown, add half a pint of broth, salt, pepper, a pickled cucumber chopped, four stalks of parsley, also chopped, and mustard; boil gently about ten minutes, add a teaspoonful of vinegar; give one boil, and serve.
Another way.—Set the chopped onion on the fire with one gill of vinegar, and boil gently till the vinegar is entirely absorbed, or boiled away. Make the same sauce as above in another pan, omitting the onion and vinegar, and when done mix the two together, and it is ready for use.
Another.—Add three shallots, chopped fine, to the chopped onion, and proceed as above for the rest.
Parisienne.—Make a bunch of seasonings with six sprigs of parsley, one of thyme, a bay-leaf, and two cloves; put it in a saucepan with half a pint of chopped truffles, and about a pint of white wine; set on the fire and boil gently till about half reduced, strain, put back on the fire, turn into it, little by little, stirring the while, nearly a pint of gravy or consommé; continue stirring now and then till it begins to turn rather thick, add pepper to taste, strain, and use with fish and game.
Poivrade.—Put a piece of butter the size of an egg in a stewpan, and set it on the fire; when melted, sprinkle in it, little by little, about a tablespoonful of flour, stirring the while; when of a proper thickness, and of a brownish color, take from the fire, add a tablespoonful of vinegar, a wine-glass of claret wine, a glass of broth, a shallot cut in two, a middling-sized onion, also cut in two, with a clove stuck in each piece, a sprig of thyme, one of parsley, a bay-leaf, a clove of garlic, a little salt, and two pepper-corns; boil about twenty minutes, strain and use.
The vinegar, shallot, and onion may be boiled separately as for a piquante sauce.
