Ok, there's just no way that Tahini goes bad in a month...LOL
I buy that like once a year, and keep it refrigerated, since you only use 2 tbsps or so for Hummus.
Didn't notice Cool Whip on there, though, and I didn't even know that that could go bad after only a week in the fridge...I bought some to put on my granddaughter's hot chocolate for her visit, but there were greenies on top of it!
Next time - marshmallows only!!!
