Notes
Storage: Keep in a sealed jar or squeeze bottle in the fridge for up to 1 week. Give it a good shake or stir before using.The oil matters: Use a neutral-tasting oil like sunflower, light vegetable, or rapeseed. Avoid olive oil — it's too strong and will overpower the whole thing.Kombu dashi powder: This is the secret ingredient that gives it that subtle umami depth — don't skip it! Find it in Asian supermarkets or online.Serve it with: Drizzle over sushi rolls, use as a dipping sauce for gyoza, spread it in a tofu katsu burger, or swirl it over okonomiyaki. Honestly, a little goes a long way.
