Tofu is made from coagulating soy milk and then pressing the resulting curds into soft white blocks. The coagulants used in the process can be natural or chemical. The most common coagulant used is calcium sulfate, which is a naturally occurring mineral. Other coagulants include magnesium chloride and nigari, which is a byproduct of sea salt production. The type of coagulant used can affect the texture and flavor of the tofu. Tofu is a popular ingredient in vegetarian and vegan cooking and is valued for its high protein content and versatility in recipes
