Thinly slice red onions, then place them in a jar or a container with a lid.
1 large red onion
Pour water inside the same jar, along with apple cider vinegar, sugar, and salt.
⅓ cup sugar, 2 cups apple cider vinegar, 1 Tablespoon salt, 2 cups water
Secure the lid, and mix well by shaking.
Store in the refrigerator until bright pink and tender. This could take anywhere from 30 minutes to overnight, depending on the thickness of your onion slices.

I like to slice my onions a little thicker for a crunch, but the thinner your onions are sliced the quicker the pickling process goes.
Try a different vinegar! Play around with different vinegar options to find your favorite flavor.
If you want to naturally sweeten your pickled onions, I recommend using maple syrup or honey.
Make your pickled onions spicy, by adding a few freshly sliced jalapeño peppers inside your pickling jar.
Add in a clove or two of garlic for a more garlicky pickled onion!
