Dashi, the Japanese Umami Base

Dashi is the foundational Japanese stock, traditionally built from just two ingredients: kombu (dried kelp) and katsuobushi (shaved dried bonito). For a vegan version, kombu alone or with dried shiitake mushrooms works beautifully. Cold steeping kombu for several hours draws out deep umami without bitterness, then a brief warming (never boiling) releases further savouriness. Toasting the kombu first, as Kristen did on the barbecue, adds a smoky dimension. Dashi is the base of miso soup, glazes, poaching liquids, and many modern vegetable dishes. Keep it simple, keep it clean, and it will lift the most humble ingredients to quiet brilliance.
