About

The radish (Raphanus sativus) is an edible root vegetable of the Brassicaceae family that was domesticated in Europe in pre-Roman times. They are grown and consumed throughout the world. Radishes have numerous varieties, varying in size, color and duration of required cultivation time. There are some radishes that are grown for their seeds; oilseed radishes are grown, as the name implies, for oil production.

Although the radish was a well-established crop in Hellenistic and Roman times, which leads to the assumption that it was brought into cultivation at an earlier time, Zohary and Hopf note that “there are almost no archeological records available” to help determine its earlier history and domestication. Wild forms of the radish and its relatives the mustards and turnip can be found over west Asia and Europe, suggesting that their domestication took place somewhere in that area. However Zohary and Hopf conclude, “Suggestions as to the origins of these plants are necessarily based on linguistic considerations.”

Cultivation

Summer radishes mature rapidly, with many varieties germinating in 3–7 days, and reaching maturity in three to four weeks.[2][3] A common garden crop in the U.S., the fast harvest cycle makes them a popular choice for children’s gardens.[2] Harvesting periods can be extended through repeated plantings, spaced a week or two apart.[4]
Radishes grow best in full sun[5] and light, sandy loams with pH 6.5–7.0.[6] They are in season from April to June and from October to January in most parts of North America; in Europe and Japan they are available year-round due to the plurality of varieties grown. Most soil types will work, though sandy loams are particularly good for winter and spring crops, while soils that form a hard crust can impair growth.[4] The depth at which seeds are planted affects the size of the root, from 1 cm (0.4 in) deep recommended for small radishes to 4 cm (1.6 in) for large radishes.[3]

Recipes and Uses

The most commonly eaten portion is the napiform taproot, although the entire plant is edible and the tops can be used as a leaf vegetable.
The bulb of the radish is usually eaten raw, although tougher specimens can be steamed. The raw flesh has a crisp texture and a pungent, peppery flavor, caused by glucosinolates and the enzyme myrosinase which combine when chewed to form allyl isothiocyanates, also present in mustard, horseradish and wasabi. Radishes are used in salads, as well as in many European dishes.
Radishes are suggested as an alternative treatment for a variety of ailments including whooping cough, cancer, coughs, gastric discomfort, liver problems, constipation, dyspepsia, gallbladder problems, arthritis, gallstones, kidney stones[13] and intestinal parasites.[14]

Glazed Radishes from Fine Cooking In Season

Ingredients

    • 1 bunch radishes, scrubbed and trimmed
    • 2 Tblsp butter
    • 1 teaspoon sugar
    • 1/4 teaspoon sea salt, plus more to taste
    • 1/2 lemon

Make radishes uniform in size by having extra-large ones. Wash and dry.
Arrange in small saute’ pan, just large enough to have in single layer.
Add the butter, sugar, and salt.
Add enough water to come halfway up the sides of the radishes.
Cover with a pot lid askew, bring to a high simmer, then lower heat and simmer gently.
Start testing after 5 minutes, but it may take up to 10-15 minutes. A knife should penetrate easily with just some resistance.
When water is mostly cooked away, and radishes are tender, squeeze lemon juice into the pan and swirl to coat the radishes.
Plate and add more, lemon or salt to taste.
