These proportions may be multiplied or divided to make larger or smaller quantities. Put the first five ingredients together in a bowl, and mix them well; then add the oil one drop at a time, stirring constantly with a wooden paddle or spoon "round and round," not back and forth. After dropping and stirring for ten minutes, the mixture will become stiff and difficult to turn. At this point stir in a little of the vinegar or lemon-juice. Then drop in more oil, and stir until it again becomes stiff. Continue putting in oil and the acids until all are used, when you should have a thick, smooth cream which, when taken up on the end of the spoon, will keep its shape and not "run." It will take from twenty minutes to half an hour to make it. Last stir in the cream.
Should the dressing "break," or appear as if curdled, it may sometimes be restored to smoothness by beating with a Dover egg-beater, or by adding more egg and stirring for a while without adding oil. If these expedients fail, begin all over again, adding the spoiled dressing to a new one. However, a mayonnaise dressing will not go wrong except in the hands of a careless worker. The only points to be observed are to put the oil in slowly, and to stir constantly and rapidly. The sweet cream is a valuable addition, giving the mayonnaise a delicate, satisfying flavor.
LETTUCE SALAD
Prepare a head of lettuce by washing each leaf separately in a stream of water, tearing off any portion that is bruised or brown, and looking carefully for little green creatures that may be lodged in the creases; they are not easily seen. Then drain the lettuce on a fresh towel or napkin, for if the leaves are very wet the dressing will not cling to them. Next tear it to pieces with the fingers, rejecting the large part of the midrib, put it into a deep bowl, pour on a French dressing, and toss it with a wooden salad-spoon and fork until all the lettuce seems oiled. Serve immediately.
Mayonnaise dressing may be used instead of the French dressing in this salad.
TOMATO SALAD
Wash in cold water and wipe some fair, ripe tomatoes. Cut them in slices one third of an inch thick. Do not peel them. Arrange some clean white lettuce leaves on a silver or china platter, with two large leaves at either end, their stems toward the middle, and two small ones at the sides. Lay on them the slices of tomato, with their edges overlapping each other. Serve with this salad French dressing.
CHICKEN SALAD
Prepare a nice chicken (one not too young) by boiling it until tender. Then set it away in its own broth to cool. (It is a good plan to boil the chicken the day before it is intended for use.) Meanwhile make a mayonnaise dressing. When the chicken has become cold, take it from the broth, and cut it as nearly as possible into half-inch cubes, rejecting all skin, tendons, cords, and bones. Season it with salt and pepper. Tear into small pieces with the fingers some tender, well-cleaned lettuce, and then mix equal quantities of chicken and lettuce with a part of the dressing; arrange it in a shallow salad-bowl, and spread the remainder of the mayonnaise over the top. The yolk of egg hard-boiled and pressed through a wire strainer with the back of a spoon, so that it falls in little crinkled pieces all over the top, makes a pretty garnish. Celery tops, the tiny inside leaves of lettuce, and parsley may be used singly or together for a border.
Chicken salad is usually made with celery instead of lettuce, but the latter is better for an invalid, although tender, delicate celery may be used. Serve a very small quantity, for chicken salad is a concentrated food, and should not be eaten in large amounts by either the convalescent or the well. The chicken, lettuce, and dressing may all be prepared beforehand, but on no account should they be mixed together until just before serving.
