A further advantage is that, in rich soil and with plenty of water, a single plant will yield two or three hearts if those of the outside leaves which are not needed for bleaching the center are left on; whereas head lettuce is never of the "cut-and-come-again" kind.
The only trouble with escarole is that it has not been educated. Lettuce has been trained by dozens of experts, the result being a large number of excellent varieties, some with heads as solid as cabbages. My object in writing to Mr. Burpee was to persuade him to give escarole a "college education"—to teach it how to head, and bleach itself, like lettuce.
He promptly replied that he would get seeds abroad of all the different varieties and experiment with them in his Fordhook trial grounds; also, that he would write to Luther Burbank and try to get him interested. Unfortunately Mr. Burbank was too busy with other reforms to take up this plant too; but Mr. Burpee forged ahead, and in November, 1912, he sent me copies of the notes on the varieties of escarole he had sowed—seventeen in all. "One or two of these," he wrote, "seemed to be much better than the Broad Leaved Batavian, but none of them are really self-folding." There seems to be hope in a variety numbered 5131 on his schedule, which is thus described: "Foliage pale yellowish-green, a robust strong grower, averaging twenty inches in diameter, leaves eight inches long by four inches in breadth, plain leaved, but slightly curved, inner leaves being much incurved, giving the impression of its being an excellent strain for bleaching."
Along those lines I have no doubt that a head-escarole will be evolved in a few years, and that the world will be indebted to Mr. Burpee for one more gastronomic delicacy as welcome as his improved head-lettuces, his limas, his stringless pod beans, and his improved melons, cucumbers, squashes, tomatoes, cabbages, and other vegetables. Mr. Burbank wrote to me under date of December 18, 1912: "It is so natural for escarole to spread flat on the ground, that it will take some time and a little pains to make it form a head." Mr. Burpee will take the time and the pains.
The bitter taste of escarole—a mere trace where the plant is well grown—is welcomed by epicures and hardly noticed by others.
The dressing is the same as for lettuce. A combination that cannot be too highly commended is tomatoes with escarole. This mixture is, I think, my favorite of all salads.
So far as tomatoes are concerned, we have nothing to learn from the French. As it is an American plant—its original home being Peru—it is proper that Americans should have a greater number of varieties and improvements than any other country.
The Germans are only just learning to like tomatoes; the English have made more progress in this important branch of gastronomic education; the French revel in the tomato; and in Italian cookery it is an important ingredient; but in the United States tomato-eating amounts to a passion, a frenzy.
In New York every corner grocery, even in the poorer quarters, has its constant supply. Apparently, all classes, rich and poor alike, are bound to have their tomatoes daily, be their price five cents a pound or twenty-five or more. For this astonishing appetite there must be good reasons. The tomato, with its delicate acid flavor is unquestionably most wholesome. Often I walk a mile to bring home the best specimens of this grand appetizer I can find; and in my vegetable garden the patch most carefully enriched and hoed and watered is that where the tomato grows.
