How does pickling work? How do you pickle red onions?
There are two types of pickling process: vinegar pickling and fermenting. Fermentation is the process of pickling something over a long period of time, but vinegar pickling can be rather quick.
By immersing a vegetable in a vinegar solution, you preserve the fresh food. This allows the food to last much longer. An added benefit of pickling red onions is that you reduce the harsh and sometimes even spicy taste of a raw red onion.
For quick pickling you can immerse the veggies in warm vinegar mixture. For more traditional pickling you want to immerse your veggies in a room temperature liquid.

How to make pickled red onions
First, slice you red onion into thin rings or slices. Then, heat the water and vinegar over high heat just until it boils. Next, allow pickling liquid to cool.
Then, add the sliced onions to the mason jar. It’s okay if you have to smush them in there to get them all to fit.
Next, pour cooled pickling liquid over the onions and allow that to sit on the counter for an hour.
Finally, close the mason jar with an airtight lid and place the onions in the fridge to chill.
Store the onions in the fridge for as long as they last, which isn’t long in our home!
