The correct phrasing of this question should likely be, "How do you store cooking oil?" Here's how to store cooking oil properly:
Cooking oils should be stored in airtight containers, ideally in dark glass bottles, to protect them from light, heat, and air, all of which can degrade the oil and affect its flavor and quality.
Here's a breakdown of best practices for storing cooking oil:
-
Airtight Containers: Ensure the oil is stored in a tightly sealed container to prevent oxidation, which can lead to rancidity.
-
Dark Glass Bottles: Dark-colored glass helps to shield the oil from light, which can break down the oil's components. If dark glass isn't available, store the oil in a cabinet or pantry.
-
Cool, Dark Place: Keep the oil in a cool, dark place away from direct sunlight and heat sources like stoves or ovens. Temperature fluctuations can negatively impact the oil's quality.
-
Refrigeration (Optional): Some oils, particularly nut oils like walnut or sesame oil, benefit from refrigeration to extend their shelf life. Refrigeration may cause some oils to become cloudy, but this doesn't affect their quality; they will clear up at room temperature.
-
Shelf Life: Aim to use cooking oils within three to six months for the best flavor and quality. While they can often remain safe to use for up to a year if stored properly (especially if refrigerated and sealed), flavor and nutritional value may diminish over time.
-
Avoid Contamination: Be careful not to introduce any contaminants into the oil. Always use clean utensils when dispensing oil from the bottle.
Summary: To maintain the quality and extend the shelf life of your cooking oils, store them in airtight, dark glass bottles in a cool, dark place, and consider refrigeration for nut oils.
