How to Choose a Good Shima Daikon
A high-quality shima daikon should have a smooth, glossy surface. Traditionally, one way to judge its quality is to gently tap the radish with a fingernail. A good one is said to produce a clear, firm “knocking” sound.
Inside, the flesh has a fine texture and cooks relatively quickly. It readily absorbs the flavors of seasonings and broth while maintaining its shape, making it particularly well suited to simmered dishes.
Ideal for Oden and Other Slow-Cooked Dishes
Shima daikon is especially popular in oden, a classic Japanese dish in which ingredients are slowly simmered in a flavorful broth. Because the radish is less likely to fall apart during cooking, it can be simmered for a long time while retaining its satisfying texture.
It can also be enjoyed as pickles or other simmered dishes, allowing its naturally mild flavor to complement a wide range of seasonings.
A Radish That Stores Well in Okinawa’s Climate
Another appealing feature of shima daikon is its excellent keeping quality. Even when left in the field for an extended period, it is relatively slow to develop “su,” the hollow or porous center that can occur as some radishes age.
This means farmers can harvest only what they need, leaving the remaining radishes in the field until they are ready to be used. This practical characteristic has long been valuable in Okinawan agriculture.
A Traditional New Year’s Food
In Okinawa, shima daikon is traditionally prepared as a vinegared dish for the Lunar New Year. It is also enjoyed in everyday home cooking, particularly during the cooler months when hearty simmered dishes are especially appealing.
When to Enjoy Shima Daikon
