A while ago, my parents came up to visit me in my apartment. They offered to do some shopping, since they had a car and I usually don't, so gratefully accepted and I sent them out with a shopping list of mine. One of the items was nutritional yeast (I like it on pasta sometimes), but the store was almost out of it. They picked up some nutritional yeast, and also some soy protein powder, which wasn't on my list. Now I have two questions:
1) It's been in my refrigerator for about a month and a half at this point. How long does it last?
2) If it's still probably good, what do I do with it?
