FAQ · Things people ask

About this recipe.

What is the best way to enjoy natto if I'm new to it?

Start by mixing it well with the provided sauce and karashi (mustard), then serve it over warm rice. The rice helps to balance the strong flavor. You can also add chopped green onions or a piece of nori seaweed for extra texture and flavor.

Why is natto so sticky?

The stickiness comes from a natural polymer called polyglutamic acid, produced during the fermentation process by the Bacillus subtilis bacteria. This sticky substance is believed to have various health benefits, including supporting gut health.
