Q: My family kept peanut butter in the fridge, but in college all my roommates kept peanut butter at room temperature and I loved how easy it was to spread! Now I keep my peanut butter at room temp too but I recently read you need to keep it in the fridge. Why? Is there a difference between PB with/without preservatives? Is my Jif OK on the shelf?

Editor: Tiffany, peanut butter is fine stored in a cool cabinet. But natural peanut butter has a tendency to separate, the oil floating to the top of the nut butter. To prevent this, many people keep their peanut butter in the fridge.

Readers, what do you do with your peanut butter? Is it in the fridge or in a cupboard?
