Ingredients

  • 1 medium red onion thinly sliced
  • ¾ cup apple cider vinegar
  • 2 tablespoons granulated sugar
  • 2 teaspoons kosher salt

Instructions

  • Place onion in quart-sized mason jar or other heat-safe container with tight-fitting lid.
  • In small saucepan, heat vinegar, sugar, salt and 3/4 cup water to a very low boil over medium heat, stirring occasionally.
  • Pour vinegar mixture over onions in jar.
  • If eating right away, place lid on container and leave at room temperature for 30 minutes, turning jar over to jostle the contents every once in awhile. Onions will be sufficiently pickled enough to eat after 30 minutes.
  • Or, for longer term storage, leave lid off jar and allow contents to cool completely to room temperature. Then, place lid on jar and refrigerate up to 1 week.
