How to cook and store fresh okara for safe consumption?
I have never heard that uncooked okara is toxic to consume, so I don't know about that part, but you could try dry roasting it in a pan until it is dry and golden brown, that would cook it and also dry it out for storing. I have made muffins and brownies with okara with success (more or less), and I've also added it to scrambled eggs for a bit of protein boost.
