COLD SAUCES.
Cold dishes, which are such a pleasing feature of foreign cookery, are much neglected with us, at least in private kitchens, or they are limited to two or three articles served in mayonnaise, or a galantine, yet the dishes which the French call chaudfroids are both delicious and ornamental, and it only requires a little taste, care, and perfect sauce to convert the ordinary cold chicken, turkey, or game into an elaborate and choice dish.
Among cold sauces, of course mayonnaise, both green, red, and yellow, reigns supreme; indeed, of late years it has become almost hackneyed. Yet no work on choice eating would be complete without the different forms of mayonnaise.
Mayonnaise is one of those sauces in which everything depends on care, and very little on skill, and yet some women have quite a reputation for making it among their friends who often declare how unsuccessful their own efforts have been, and that to succeed is a gift. It is not as a novelty, therefore, that the manner of making it is given here, but that those who believe they have not the “magic fingers” may take courage and try again.
First of all let me explain what seems to puzzle many. I have been frequently asked, “How much oil can I use to two eggs?” the answer is, “As much as you choose;” or, again, “How many eggs ought I to take to a quart of oil?” again the answer is, “One, two, three, or four.” The egg is only a foundation, and mayonnaise will “come” no better with two yolks than one, although some chefs consider it keeps better when two eggs are used to a pint of oil.
A cool room is always insisted on for making the sauce, but to the amateur I say, oil, eggs, and bowl also, should be put in the ice-box until well chilled, and even then mishaps may come from using a warm spoon from a hot kitchen drawer or closet; that, therefore, must be cool also. Of course it is often successfully made with only the usual precaution of a cool room, but with everything well chilled it is hard to fail.
If very little of the sauce is wanted, one yolk of egg will be better than two. Separate the yolks very carefully, allowing not a speck of white to remain; remove also the germ which is attached to the yolk. Stir the yolk at least a minute before beginning to add oil; then arrange your bottle or a sharp-spouted pitcher in your left hand so that it rests on the edge of the bowl, and you can keep up a pretty steady drop, drop, into the egg, while you stir with your right steadily. The oil must be added drop by drop, but this does not mean a drop every two or three minutes; you may add a drop to every one or two circuits of the spoon. The reason for adding it slowly is that each drop may form an emulsion with the egg before more goes in. After two or three minutes look carefully at the mixture; if it has not begun to look pale and opaque, but retains a dark, oily appearance, stir it steadily for two minutes, and then add oil slowly, drop by drop, stirring all the time. If it has not now begun to thicken, it probably will not; but the materials are not lost. Put the yolk of another egg into a cool bowl, and begin again using the egg and oil you have already mixed, in place of fresh oil. When this is all used, proceed with the oil (it is hoped, however, that the work will have proceeded without the necessity for beginning afresh). When the mayonnaise becomes quite thick, use a few drops of vinegar to thin it; then more oil, until sufficient sauce is made. Then white pepper and salt should be added for seasoning. The vinegar used should be very strong, so that very little of it will be sufficient to give the necessary acidity, without making it too thin. This is especially the case when the sauce is required to mask salad. It should for this purpose be set on ice until firm, but in all cases be kept cold. The best mayonnaise, left in a warm kitchen, would separate and become oily. The stirring must be steady and constant, and the task must not be left until completed.
Mayonnaise is the basis of several other sauces, so that in accomplishing it a great deal is done.
