  • 1 red onion, peeled and thinly sliced
  • ⅓ cup apple cider vinegar

  • 1 Tbsp. salt
  • 2 cloves garlic, peeled (optional)


  1. Put onions in a jar or lidded container.
  2. In a medium bowl, mix together both vinegars, warm water, sugar, and salt until the salt and sugar are dissolved.
  3. Add any additional flavorings like garlic to the jar.
