Naturally Brewed Soy Sauce
The essence of East Asian (umami) flavour in a bottle: soybeans, wheat, water and salt, naturally fermented for many months. Because it is used by the teaspoon, its carbohydrate is very low and the glycemic index does not apply, and it adds depth of flavour that replaces added salt and fat.
