Expiration & Storage Tips
When does pickled red onion expire?
Unopened jars of pickled red onions can last up to a year when stored in a cool, dark cupboard. Once opened, they can still last for about 2 months in the refrigerator. Homemade pickled red onions, on the other hand, stay fresh for 2-3 weeks when refrigerated. If frozen, which is not commonly done, the texture might change but they can last indefinitely.
How do you tell if pickled red onion is bad?
The first sign that your pickled red onions have gone bad is a noticeable change in their smell. If they give off an off-putting or sour smell, it's best to discard them. Additionally, if you spot any signs of mold, it's time to say goodbye. Changes in color from vibrant pink to brown or a slime-like texture are also indicators of spoilage.
Tips for storing pickled red onion to extend shelf life
• Always refrigerate your pickled red onions after opening the jar to prolong their shelf life.
• Use clean utensils to take out the onions from the jar to avoid introducing bacteria.
• Homemade pickled onions should be stored in sterilized jars.
• Despite the common belief that vinegar-based products don't require refrigeration, it's always a good idea to store pickled items in the fridge.
• Keep them in the original brine. The vinegar solution acts as a natural preservative.
