Inventory, bunch : 0
Description/Taste
Purple Daikon radishes are medium to large roots, averaging 15 to 25 centimeters in length, and have an oblong, cylindrical appearance with blunt, curved ends. There are also dwarf varieties that are smaller in size, tapering into a single taproot. The radish’s skin is semi-smooth, textured, and firm, showcasing light purple to violet hues. Underneath the surface, the flesh is dense, crisp, and bi-colored, streaked with purple stripes over a white base. The flesh may also feature a dark purple ring around the edge of the flesh, just below the skin. Purple Daikon radishes contain less water than white daikon varieties and retain a crunchy, snap-like core even when grown to larger sizes. The radish also bears a mild, subtly sweet, and peppery flavor. The sharpness of the root will vary depending on the specific variety and the climate where the radish is grown. Hotter temperatures will produce pungent, spicier roots, while cooler climates will create mild, slightly peppery radishes. Once cooked, the flesh softens to a consistency similar to a potato and develops a neutral flavor. Purple Daikon radishes also grow dark green, serrated leaves that are edible and have a vegetal, peppery taste.
Seasons/Availability
Purple Daikon radishes are available year-round, with a peak season in the winter through spring.
