Help! I just made my pumpkin pie filling with canned pumpkin, cream, sugar, eggs & spices. It tastes delicious right now, unbaked. But I just saw that one of the cans I used has an expiration date 11/2018. In fact, that’s the one I used the most of, and what’s left in the can doesn’t taste very good. Not horrible, just not as good as the one that expires in 2020. Do I need to start over?
