Under cultivation, the turnip forms an agreeable culinary esculent; but on account of the large proportion of water entering into its composition, its nutritive value is exceedingly low. The Swedish, or Rutabaga, variety is rather more nutritive than the white, but its stronger flavor renders it less palatable. Unlike the potato, the turnip contains no starch, but instead, a gelatinous substance called pectose, which during the boiling process is changed into a vegetable jelly called pectine. The white lining just inside the skin is usually bitter; hence the tuber should be peeled sufficiently deep to remove it. When well cooked, turnips are quite easily digested.
Preparation and Cooking.—Turnips are good for culinary purposes only from the time of their ripening till they begin to sprout. The process of germination changes their proximate elements, and renders them less fit for food. Select turnips which are plump and free from disease. A turnip that is wilted, or that appears spongy, pithy, or cork-like when cut, is not fit for food.
Prepare turnips for cooking by thoroughly washing and scraping, if young and tender, or by paring if more mature. If small, they may be cooked whole; if large, they should be cut across the grain into slices a half inch in thickness. If cooked whole, care must be taken to select those of uniform size; and if sliced, the slices must be of equal thickness.
RECIPES.
Boiled Turnips.—Turnips, like other vegetables, should be boiled in as small an amount of water as possible. Great care must be taken, however, that the kettle does not get dry, as scorched turnip is spoiled. An excellent precaution, in order to keep them from scorching in case the water becomes low, is to place an inverted saucer or sauce-dish in the bottom of the kettle before putting in the turnips. Put into boiling water, cook rapidly until sufficiently tender to pierce easily with a fork; too much cooking discolors and renders them strong in flavor. Boiled turnips should be drained very thoroughly, and all water pressed out before preparing for the table. The age, size, and variety of the turnip will greatly vary the time necessary for its cooking. The safest rule is to allow plenty of time, and test with a fork. Young turnips will cook in about forty-five minutes; old turnips, sliced, require from one and a quarter to two hours. If whole or cut in halves, they require a proportionate length of time. White turnips require much, less cooking than yellow ones.
Baked Turnips.—Select turnips of uniform size; wash and wipe, but do not pare; place on the top grate of a moderately hot oven; bake two or more hours or until perfectly tender; peel and serve at once, either mashed or with cream sauce. Turnips are much sweeter baked than when cooked in any other way.
Creamed Turnips.—Pare, but do not cut, young sweet white turnips; boil till tender in a small quantity of water; drain and dry well. Cook a tablespoonful of flour in a pint of rich milk or part cream; arrange the turnips in a baking dish, pour the sauce over them, add salt if desired, sprinkle the top with grated bread crumbs, and brown in a quick oven.
Chopped Turnips.—Chop well-boiled white turnips very fine, add salt to taste and sufficient lemon juice to moisten. Turn into a saucepan and heat till hot, gently lifting and stirring constantly. Cold boiled turnip may be used advantageously in this way.
Mashed Turnips.—Wash the turnips, pare, and drop into boiling water. Cook until perfectly tender; turn into a colander and press out the water with a plate or large spoon; mash until free from lumps, season with a little sweet cream, and salt if desired. If the turnips are especially watery, one or two hot, mealy potatoes mashed with them will be an improvement.
