Ingredients

  • 1 1/2 cups red onion thinly sliced
  • 1 small garlic clove halved
  • 6 black peppercorns
  • 1 small sprig fresh thyme
  • 3/4 cup apple cider vinegar
  • 1 cup water
  • 1 tablespoon granulated sugar
  • 1 1/2 teaspoons kosher salt

Instructions

  • Place the onions in a jar along with the garlic, peppercorns and thyme.
  • Place the apple cider vinegar, water, sugar and salt in a small pot over medium high heat.
  • Bring to a simmer. Cook for one minute, or until sugar and salt have dissolved.
  • Carefully pour the liquid into the jar of onions. Let the jar sit at room temperature for one hour.
  • Cover the jar and refrigerate. Let it sit for at least two hours before serving, or up to two weeks.

Notes

  1. I use a mandoline to cut my onions into perfect thin slices. You can slices the onions into rings, or else cut the onion in half lengthwise before you make your slices.
  2. While this recipe calls for the onions to marinate in a glass jar, any airtight glass or plastic container will also work.
