We're still in prime root vegetable season, and there's one that stands out as the beauty of the bunch: the watermelon radish. You'd never know it from their pale white and green exterior, but the inside holds a vibrant, peppery surprise. Here's everything you need to know about watermelon radishes.
Why Is It Called a Watermelon Radish?
Watermelon radishes are an heirloom variety of daikon radishes and originated in China, where they are called shinrimei. They're a root vegetable and member of the Brassica family, which also includes arugula, broccoli, and cabbage.
The watermelon radish doesn't actually taste like watermelon. Instead, the flesh, which is green around the exterior with a deep pink to bright red center, bears quite a resemblance to its namesake.
Watermelon radishes are larger than regular radishes and can range from the size of a golfball to that of a softball. They're firm and crisp with a mild taste that's a blend of slightly peppery and slightly sweet.
How to Buy and Store Watermelon Radishes
Watermelon radishes are widely available from late fall through spring. These beautiful vegetables thrive in cold soil.
When buying them, choose radishes that feel heavy for their size. They should be firm and without blemishes.
Store them in a plastic bag or container in the crisper drawer of your refrigerator for up to a few weeks.
How to Use Watermelon Radishes
These pretty radishes aren't all show — they're also really delicious and versatile! Watermelon radishes can be eaten raw, pickled, or cooked. They can be braised or roasted like a turnip, or mashed like a rutabaga, though I prefer them raw since they lose their bright hue when cooked.
Similar to regular radishes, this variety does not have to be peeled before eating. Just make sure to wash them very well, and scrub away any dirt.
