Expiration & Storage Tips
When does chili oil expire?
Chili oil has a longer shelf life than you might expect. When unopened, it can last for about two years if stored in a cool, dark place. The printed date on the package should be a good guide for its shelf life even if unopened, so don't exceed this if possible. Once opened, you'll need to store chili oil in the refrigerator to keep it fresh. In the fridge, it usually lasts for about six months to a year. Lastly, if you've ventured to make your own chili oil at home, aim to use it within two to three months for optimal taste and quality. As for freezing, it's not typically necessary or recommended for chili oil.
How do you tell if chili oil is bad?
To determine if your chili oil has gone bad, you'll need to pay attention to the smell and visual aspects. If it smells rancid or off, that's your first sign that it's expired. Additionally, if you notice any discoloration or mold growth, those are sure signs it's time to toss it. Bear in mind that chili oil should retain its vibrant red-orange color; any dull or darkened color might mean it's past its prime. Furthermore, any change in texture or viscosity should alert you to possible spoiling.
Tips for storing chili oil to extend shelf life
• Always keep the chili oil bottle tightly closed when it's not in use.
• Keep your chili oil in a cool, dark cupboard or in the fridge to prolong its life. Cold storage really helps to slow down the oxidation process, thus preserving its unique flavors.
• Try and use a clean, dry spoon every time you dip into the chili oil, as introducing water or food particles can promote bacterial growth.
• If you are making homemade chili oil, ensure that the container you're using to store it is clean and dry.
