Anyways, I froze a block of tofu, because I wanted the spongy texture that everyone has been talking about, and it also seemed like a good way to preserve it. I just took it out of the freezer today, and it's a yellowy color. Like iced pee or something (not to be gross). Would it be ok to eat still, and how long will it take for it to thaw? I'm very hungry and want to make a marinade and eat the tofu with some spinach and rice. Any help would be great.
