Frequently asked questions
How long do pickled red onions last?
You can safely keep your pickled red onions in the refrigerator for about two weeks. But since they are so good and can be used for everything from eating raw to adding as a topping, they do not usually last that long anyway.
Which vinegar is best for pickling?
Although distilled white vinegar is the most common choice, this does not necessarily mean it is the best choice for you. The acid content in white vinegar is high and the flavor is mellow, so it works well for all kinds of pickling.
I used rice wine vinegar in this recipe because it has a nice mild taste. Malt vinegar is also a good choice and has a very bold flavor. Cider vinegar is okay, but you have to pay attention to the acidity since many kinds of cider vinegar do not have the 5% acid you need for pickling.
What is the difference between pickling and canning?
When pickling, you use some type of brine like vinegar and salt as pickling liquid. You typically use a mason jar but a glass or ceramic jar with a tight-fitting lid will also work. On the other hand, the canning process is done by using boiling water, salt, and pressure to kill any bacteria and seal in an airtight container. Anything that is canned will last for months while pickling only lasts a couple of weeks.
- Alternatively, microwave the vinegar mixture. Cook on high until it reaches a simmer and then add the onions and other ingredients as stated.
- Also, add more water or blanch the onions first for a more mellow onion flavor.
- For less sugar in your pickles, use a sugar substitute instead of white sugar.
- These tangy onions would be perfect in a salad such as this avocado chicken Caesar salad, easy cucumber salad, or with this amazing BLT salad recipe.
