Can you eat expired flour?
Quick Answer
Yes, but with caution.
Flour doesn’t really expire, but it can go bad. The ‘best by’ date on the packaging is a guide for optimal quality. However, if the flour has been stored properly and shows no signs of infestation or rancidity, it can still be used past its ‘best by’ date.

How to Tell
