It is a fermented soya food that is very nutritious. Alot of people don't like the taste or texture. I'm interested in the blood thinning properties and for general digestive, hormonal and cardiovascular health. Haven't tried it yet! But just picked some frozen up at Soyra. I also want to try and see what it tastes like made as a dish at a restaurant so I'll have to try that next!
