Select tart, juicy apples. Cut in quarters, pare and core and cut in 1/2-inch cubes. Add half as much celery, washed, scraped, and cut into cubes. Mix with boiled or mayonnaise dressing and serve cold on lettuce leaves. If handsome red apples can be had, they may be washed and polished and a slice cut from the stem end and the apple used as a cup after scooping out the inside to use for a filling with the celery. Serve on a lettuce leaf. Chopped nuts may be mixed with the apple and celery if desired. =7. Stuffed tomato salad.= _Ingredients._ Tomatoes, medium sized Boiling water Salt Cucumbers (or celery) Mayonnaise dressing Lettuce leaves _Method._ Cover medium sized tomatoes with boiling water for a minute and remove the skin. Cut a thin slice from the top and take out part of the seeds and pulp. Sprinkle inside of the tomato with salt, invert, and let stand one half hour. Fill tomatoes with cucumbers (or celery) cut in small cubes and moistened with mayonnaise dressing. Arrange on lettuce leaves and garnish top with mayonnaise dressing. _Laboratory management._——1/2 egg yolk (1 teaspoonful) and 1/4 cup of olive oil is as small a quantity as is practicable to use in making the mayonnaise. This quantity made by groups of two works out well as the process of adding the oil drop by drop is difficult for a beginner working alone. The boiled dressing works in well as a variation of the boiled custard. DESSERTS The dessert in this country includes the sweet dish, or the fruit at the end of the meal. In simple meals the dessert is usually one of the two, although in more elaborate meals fruit is served after the sweet dish, and sometimes crackers and cheese are served at the last. From the point of view of nutrition and digestibility this is more than is necessary, and you will notice that when both are served, the fruit is often declined. Like the salad, the dessert may be made from a large variety of materials and bears different names. There are hot puddings and cold puddings, pies and tarts, jellies and ices and ice creams. It is very interesting to read over the many dishes of this class in a cookbook and to attempt to classify them. If you are fortunate enough to have access to a cookbook of the eighteenth century, you will find that much labor was given to the preparation of elaborate structures which served as table ornaments; even now you will find French cooks who spend much time in making elaborate displays of their skill. For everyday life the dessert should be attractive to the eye and yet simple. =Materials used in desserts.= _Eggs, milk, and cream_; these are important and are used in custards, in dishes stiffened with gelatin or thickened with cornstarch, or in ice cream.
