Query: Impractical recipes

This book contains a lot of useful information about nutrition, ingredients, and the differences in cheese vs. uncheese. Having said that, I have to admit I didn't find these recipes very useful. I can't vouch for taste because I didn't actually try any of the recipes. Most of them require ingredients that can only be found in a whole foods store, like nutritional yeast flakes or miso paste. You also have to plan in advance to prepare some of the recipes, like the imititation feta cheese which has to be marinated for 2 days to a week before it attains flavor. I didn't think it would be worth the effort to approximate the taste of cheese; I'd rather have the real thing. If you really need a substitute for cheese, it might be worth a shot, but if you're a real cheese lover, you might be disappointed.
