How to store Peanut Butter
In the pantry: 180 days
Store Peanut Butter on a middle shelf of the fridge, never the door — temperature swings every time someone opens it. Aim for 1–4°C and keep the original container sealed. Open dairy absorbs nearby odors quickly, so don't store next to strong-smelling foods. For longer storage, freezing is possible but the texture suffers after thawing, so plan to use frozen dairy in cooking, baking, or smoothies rather than eating plain.
