How to Correctly Store Cooking Oils

Heart-healthy cooking oils—such as olive, walnut, or avocado oil—have become popular in the kitchen as people seek to cook healthier dishes; however, you must be careful how you store such oils. The Cleveland Clinic offers these recommendations to ensure that you’re cooking with the best oil: over time, exposure to light or heat can affect the taste of oil, so store it in a cool, dark place; if your oil begins to taste a bit off, replace with a fresh bottle; grapeseed and walnut oils should be stored in the refrigerator, as they can become rancid quickly; most other oils can be refrigerated; and though refrigerated oils may appear cloudy, that effect disappears when they reach room temperature.
