Wasabi and Soy Sauce: How Much to Use and Why Not to Mix Them

At a good sushi counter, you may need neither — the chef has already added wasabi and brushed on soy. At casual places, use a little of each, separately. Stirring wasabi into a pool of soy dulls both and drowns the fish.

The basics. At a counter: wasabi is usually inside the nigiri, and glazed pieces need no soy. At casual places: put a small dab of wasabi on the fish, dip fish side down, lightly. Don't: mix wasabi into soy, soak the rice or fill the dish. Sashimi: a dab of wasabi on the slice, then a light dip.

Why not mix them?

Real wasabi's aroma is delicate and fades quickly; stirring it into soy dilutes the flavour and the heat. The murky mix also coats fish in too much salt. Traditionally, wasabi goes on the fish and soy is a light accent.

How much soy?

Pour a small amount — enough to cover the bottom of the dish. Dip only the fish; rice soaks up soy, falls apart and becomes salty. Soy sauce is high in salt and usually contains wheat. See soy sauce types and gluten-free sushi.

How much wasabi?

A tiny amount. Many belt chains serve wasabi separately in sachets. Most of it is horseradish-based; real wasabi is milder and sweeter. See nori, wasabi and gari.

Don't like wasabi? Ask for sabi nuki — no wasabi. It's a normal request.

When to skip soy: glazed nigiri · anago and unagi · marinated tuna (zuke) · ikura · pieces served with salt and citrus.

Going easy on soy is kinder to your health too. A light dip keeps your salt intake down.
