An essential ingredient for traditional style tofu, liquid nigari is an all-natural product from the sea that helps to curdle soy milk to produce tofu. Our liquid nigari is created through our sustainable sea salt harvesting process. This mineral-rich brine consists of magnesium chloride, as well as magnesium sulfate, calcium sulfate, and potassium chloride. It is this concentration that gives nigari its strong bitter taste (Nigari is from the Japanese word for bitter). 236 ml.
