About Komatsuna

Komatsuna is a leafy Japanese brassica vegetable, often called Japanese mustard spinach in English. Its leaves and tender stems are used raw when young or cooked in stir-fries, soups and other dishes. It is sold as bunches of leaves and stems, with younger and more mature plants differing in tenderness.

The leaves are smooth, green and oval to spoon-shaped, attached to pale green stems. The texture is tender but can remain pleasantly firm after cooking; the flavour is mild, green and slightly mustard-like. It is commonly eaten fresh or cooked, and the preparation state affects its texture and measured composition.
