The Tomato I THE TOMATO IS A GREAT FOOD AND CROP PLANT Vegetable, Fruit or Berry,--what is the tomato? A standard query this is and many an argument has raged about it. The answer is easy. It is all three. By culture and use, it is a vegetable; botanically it is a fruit and among the fruits, it is a berry being indehiscent (non-shedding), pulpy, with one or more seeds that are not stones. And they say the tomato is more truly a berry than the raspberry. But that doesn't make much difference. The thing that matters is that people like the tomato. It is easy to grow and nearly every home garden has it. It is good to look upon--shapely, colorful and of glossy sheen. A trained single stem plant with ripening fruit is a genuine ornament in the garden. It is most gratifying to the palate, fresh or cooked; soft and grainy, smooth and juicy in texture, sweet and tart and with an appealing flavor all of its own that few fail to relish. As juice or cocktail, adding color and flavor to soup, as condiment or as side dish with the entree, as salad freshly sliced or in jell, it is welcome with almost every course and some ingenious chef or, more likely, some clever housewife will, one of these days, fashion from it the dessert supreme. Nor have we exhausted the list of forms in which the tomato may be served. In addition to its simplest cooked form, stewed or turned hot from the can, it may also be baked, stuffed or not, or it may be escalloped and cooked with rice, spaghetti or other foods. Fried, before fully ripe, and served with brown gravy, it is most popular in many a home. Ketchup or catsup is one of our most widely used condiments and chili sauce many like even better. Green tomato pickles, chow chow, piccalilli carry the piquant tang of the tomato to enliven the winter table. And tomato juice, plain or dressed up with spices, vinegar or lemon juice has become a great staple of our groceries, a standard send-off for any meal from breakfast snatched on the morning sprint to work on through to the most elaborate of banquets. The tomato, by reason of its natural acidity, is readily sterilized and so can be preserved easily in glass or tin. It ranks first among the "big three" canned vegetables; the other two being sweet corn and peas. By far the great bulk that goes to the factory is put up with the addition of nothing more than salt. In addition to the condiments, puree and paste are manufactured in commercial quantities. The Italians dry tomatoes extensively in the sun, slicing the fruits, and later flavoring them to taste for various winter uses.
