It happens pretty much every year, I buy too much sour cream for the Hanukka latkes and wind up with leftover (usually around 1-1 1/2 cups). I try to eat healthy most of the time, so it's not a food product I have a great deal of use for normally. But I find it really difficult to throw it out, even if it cost less than $2.00. And to re-purpose it into baked goods - which I could give away - would involve buying more ingredients which I don't have in the pantry. Which seems like another level of waste.
How many others face ingrained guilt over throwing away "perfectly good food" - even if it is a stupid container of sour cream?
