Craft-your-own tofu at home. Our tofu coagulant is a premium food grade nigari. It is 100% vegan, gluten-free & gmo-free. While handcrafting traditional japanese tofu, our tofu coagulant is a key ingredient. It makes the tofu much softer and gives a much smoother texture than any other coagulant. Make up-to 3 kilos of block or firm tofu with one pack.
