Radish

Is a cool-season, fast-maturing, easy-to-grow vegetable. Garden radishes can be grown wherever there is sun and moist, fertile soil, even on the smallest city lot. Early varieties usually grow best in the cool days of early spring, but some later-maturing varieties can be planted for summer use. The variety French Breakfast holds up and grows better than most early types in summer heat if water is supplied regularly. Additional sowings of spring types can begin in late summer, to mature in the cooler, moister days of fall. Winter radishes are sown in midsummer to late summer, much as fall turnips. They are slower to develop than spring radishes; and they grow considerably larger, remain crisp longer, are usually more pungent and hold in the ground or store longer than spring varieties.

Pull radishes when they are of usable size (usually staring when roots are less than 1 inch in diameter) and relatively young. Radishes remain in edible condition for only a short time before they become pithy (spongy) and hot. Proper thinning focuses the harvest and avoids disappointing stragglers that have taken too long to develop.
Summer and winter radishes are most often eaten raw. Use a stiff vegetable brush and scrub radishes under cold running water. Do not peel summer or black radishes. Pare away the top and root end then slice, dice, shred, or serve whole. Large Chinese and Japanese varieties hold up well during cooking. They can be eaten raw, preserved or substituted in any recipe calling for turnips.

Daikon radishes are thought to aid in digestion, especially the digestion of fatty foods. It is a common ingredient in Japanese cooking and is always grated and added to tempura dipping sauce. Young daikons can be eaten raw but the larger (more than 8 inches long) ones must be cooked. Always peel daikons. Cut up and simmered in stews and soups, daikon tastes light and refreshing rather than heavy or starchy. Daikons are often cut into paper-thin slices by talented Japanese chefs.
