Karashi Sumiso Mustard Miso Dressing
Japan — karashi sumiso documented in Edo period cooking texts as spring vegetable dressing
Karashi sumiso (からし酢味噌) is one of Japan's most important dressings for blanched vegetables and seafood — a mixture of shiro-miso (white miso), rice vinegar, sugar, and karashi (Japanese hot mustard) creating a sweet-sour-spicy-savory balance unlike any other Japanese condiment. The mustard provides heat that dissipates quickly, the vinegar provides bright acidity, the miso provides umami and body, and the sugar rounds everything. Classic applications: blanched wakame seaweed, briefly blanched octopus (tako no karashi sumiso-ae), and spring vegetables. It must be dressed at service — the moisture continues to develop if left.
