I have only had hummus a couple times. Each time it was from a Mediterranean market. The lady who provided the hummus said it was better than she has made and less time and expense was worth it. So your choice. There are many recipes and usually, according to her, a good stir refreshens. Just depends on the amount you need and how soon you would be using it again. Maybe it would be worth it to buy couple containers and only use as needed instead of opening a larger container and having it not so fresh the next time. I do that with sour cream. Don't use it a lot but sometimes within a couple weeks depending on use by date.
