tofu
Tofu is a food made of condensed soy milk that is pressed into solid white blocks in a process quite similar to cheesemaking. It originated in China.
Rumor has it that a Chinese cook discovered tofu more than 2,000 years ago by accidentally mixing a batch of fresh soy milk with nigari.
Nigari is what remains when salt is extracted from seawater. It is a mineral-rich coagulant used to help tofu solidify and keep its form.Tofu is also a really great protein source for vegans.
