How to use and rehydrate dried komatsuna
Komatsuna, with its mild flavor, is a versatile vegetable that pairs well with any cuisine, whether Japanese, Western, or Chinese. We've separated the leaves and stems and dried them to make them even easier to use, bringing out their umami. You can enjoy a creamy sweetness within its rich flavor.
This time, we'll introduce three ways to rehydrate dried komatsuna. We'll also share the textures you can enjoy with each method and recipe ideas, so please use them as a reference.

It's incredibly versatile, whether you're quickly adding it to a finished miso soup or making namul with the moisture from wakame. It's also perfect for preparing staple single-serving dishes like simmered fried tofu or cream stew with chicken or bacon.
【10-minute rehydration】Slightly firm and crispy texture

Stir-fries and miso soup |
When dried komatsuna is rehydrated in water for about 10 minutes, it retains a slight firmness while offering a crisp texture. This rehydration method is recommended for dishes where you want to leverage komatsuna's unique texture.
For example, quickly stir-frying it with eggs adds a crispness, resulting in a dish rich in texture. When added to miso soup, its firmness becomes an accent, and the flavor of komatsuna spreads with every bite. This 10-minute rehydration is ideal when you want to thoroughly enjoy a crisp bite in your cooking.
【Half-day rehydration】Crisp yet tender to the core
| Rehydration time |
Approx. 12 hours |

Suitable dishes |
Pasta, general cooking |
When rehydrated in water for about half a day, the komatsuna absorbs moisture thoroughly, even to the core of its stems, resulting in a soft yet crisp texture that is pleasant to bite. When prepared this way, komatsuna can be served as *ohitashi* (blanched greens with dressing) with soy sauce and bonito flakes, offering a smooth mouthfeel and allowing you to fully enjoy its natural flavor.
Furthermore, when rehydrated komatsuna is mixed with pasta, the soft crispness of the stems perfectly matches the chewy texture of the pasta, making it enjoyable as a Japanese-style pasta. This rehydration method is versatile and can be widely used in stir-fries, stews, soups, and salads.

【Summary】Enjoying versatile dried komatsuna deliciously
Komatsuna enjoyed in salads is appealing for its rich aroma. However, heating often causes this aroma to be lost. Komatsuna slowly dried at a low temperature retains its fragrant flavor, offering a fresh taste close to raw.
Dried komatsuna is a versatile vegetable that can be added to miso soup as-is. By rehydrating it, the core becomes crisp and crunchy, allowing it to be used in various dishes such as pasta and jeon.
