Difference between quick pickling, pickling and fermenting

Let’s explore the difference between these methods. Pickling, quick pickling, and fermenting are all food preservation methods.

Quick pickling, also known as refrigerated pickling, is similar to marinating. It doesn’t require canning and has a relatively short storage life.

Pickling, on the other hand, requires a strong brine, heating, sterilization, and canning. This method helps preserve the food for years, but it may result in the loss of many potential health benefits.

Fermenting, in contrast, is different from pickling as it involves bringing with just salt and water. Fermentation takes at least several days to allow lacto-fermentation to develop. This process also offers numerous potential health benefits, such as vitamins and probiotics

How to make quick pickled red onions?

Ingredients

Onions – in this recipe I use red onions, but you can use any other type of onions as well.

Apple cider vinegar – use raw, unfiltered vinegar that doesn’t contain sugar and other artificial additives but contains “mother”. “Mother” looks like small clots at the bottom of the bottle and makes the vinegar cloudy when you shake it. 

Sweetener of your choice – use any sweetener you like. For keto options, you can choose between erythritol, allulose, xylitol, monk fruit and others. I usually use erythritol.

Spices – I mostly use basic spices like bay leaf and peppercorns , but there are plenty of options you can choose from. Try adding cloves, coriander, anise, chili flakes or cumin to give a punch of flavor. 

Salt – use a salt you like. Some of the healthiest options are: Himalayan pink salt, sea salt, Celtic sea salt, kosher salt. 

Boiling water to dissolve the sweetener and salt.

  • Cutting board and knife OR mandolin
  • Medium heat proof jar

Variations of the recipe

There are many recipes for quick pickled red onions, and the process and proportions can vary from one another.

In my recipe, I use a relatively small amount of vinegar and basic spices because I like a gentle acidity and overall taste. 

However, if you prefer a brighter taste, I encourage you to experiment with proportions. You can add more vinegar, different spices, less or more sweetener, and salt to find your ideal combination for your own recipe.

Anyway, I really love this recipe because you can get amazing results in a snap without any additional effort.

When quick pickled onions are ready?

Wait 30 minutes and allow the liquid to cool. They will be ready to be eaten.

However, if you have extra time, I recommend refrigerating onions for a few hours for the best results.

On the next day, the acidity of the onions will be a bit stronger but they will maintain crunchy texture. 

Even so, you can experiment and try different time scenarios to determine what you like the most.

How to store quick pickled red onions and how long do they last?

To store: in the fridge for up to 1 week.

Make sure that you use a clean jar and that onions are completely covered with brine. 

To freeze: I don’t recommend freezing pickled onions as it can affect their texture and taste.
