- 1 red onion, thinly sliced
- 1 cup apple cider vinegar
- 2 tbsp sugar
- 1 tbsp kosher salt
- 2 cups water
- Whisk vinegar and seasonings with water until fully dissolved.
- Place onion slices in a container and add liquid until covered. 1 quart mason jars work perfectly for this.
- Let sit for at least 1 hour, but it is best if left in the fridge overnight.
