7 Foods You Should Refrigerate

You might buy juice, natural peanut butter and ketchup at room temperature, but be sure to keep it in the fridge after it's opened.

We straightened out some misconceptions about foods that don’t go in the fridge. Now here are 7 foods that will benefit from the chill of the icebox.


Restaurants go through a bottle in no time, but most home kitchens don’t. Keep  ketchup fresh in the refrigerator for up to 3 months.


All those oils can and will turn rancid at room temperature (ick!). Store all your buttery goodness in the fridge or the freezer. Defrost frozen sticks in the refrigerator overnight.


Whether you buy it warm or cold, once you crack open the sealed cap, juice needs to stay cool. Are open bottles of juice hogging space in your fridge? Make homemade ice pops.

Natural Peanut Butter

No preservatives here! Keep natural  peanut butter fresh and prevent separating by storing in the chill of the fridge.

Maple Syrup

Prevent the growth of mold or yeast (which loves sugar) by storing syrup in the refrigerator for up to 3 months.

Salad Dressing

Dressings, especially ones made with dairy, fruit or citrus need to be preserved after opening. Even if you make your own, keep it chilled.

Sesame Oil
