Equipment

1 19-24oz wide mouth mason jar with lid

Ingredients

2 medium red onions, peeled and thinly sliced
½ cup apple cider vinegar
½ cup white vinegar
1 tablespoon coconut sugar
½ teaspoon sea salt
1 cup hot filtered water

Instructions

Peel your red onions. Grab a sharp knife and cut the onion in half, widthwise. Next, thinly slice the red onions.
Place the water in a microwavable bowl and heat it in the microwave for about 1 minute and 15 seconds
Add the coconut sugar to the bottom of a 16oz-24oz wide-mouth mason jar. Add the rest of the ingredients in this order: sliced red onions, apple cider vinegar, white vinegar, salt, and lastly, add the hot water. The goal is to completely cover the onions with liquid, to the very top of the mason jar. Add additional hot water as needed.
Secure the lid and give it a good shake until the coconut sugar has dissolved.
Place the jar of onions into the refrigerator for at least 30 minutes however I prefer the flavor after marinating overnight. In other words, I recommend preparing them the night before.

Notes

While technically you can eat the pickled onions after only 30 minutes of marinating, the longer they marinate the more flavor they produce. Therefore, I recommend making them the night before you plan on eating them.

If you are working with a smaller mason jar, simply evenly reduce the amount of liquid (equal parts hot water to vinegar.)

You can swap out the white or apple cider vinegar for red wine vinegar or white wine vinegar. I do not recommend any other varieties.

Make sure that your filtered water is hot. The goal is to dissolve the coconut sugar.
