Sobre este ingrediente
Liquid bittern obtained as a by-product of seawater salt production. Primarily magnesium chloride (60–95%) with minor calcium and potassium. Indispensable as the coagulant for traditional Japanese tofu, and increasingly used as a magnesium-supply ingredient in hot-pot soups, beverages, and cosmetics. Domestic production is concentrated in Okinawa (Ishigaki, Miyako), the Seto Inland Sea (Ako, Kagawa), and Noto Peninsula. Mass-volume nigari for tofu manufacturing flows through cooperatives, while specialty single-origin nigari has emerged as a premium retail and wellness category.
