Sea Vegetable
Oarweed
A tier
Oarweed is the folk name for Laminaria digitata—thick, strap-to-fingered kelp that looks like paddles in the tide. Dried oarweed gives a bold sea stock for stews; fresh young tips can be cooked as a sea vegetable side. It is Atlantic kombu’s working-class cousin—honest, iodine-bright, less aristocratic than Rishiri. Rinse lightly, simmer for broth, or toast carefully for snacks. Strong flavour means use less than delicate Japanese kombu if substituting in dashi ratios.
