  • Peppercorns optional
  • 2 garlic cloves optional
  • 1 cup apple cider vinegar or white vinegar

  • Put some peppercorns and the garlic in the container with the onions if using.
  • Place a small sauce pan over medium high heat. Add the vinegar, water, sugar and salt. Stir to combine and heat until the sugar dissolves.
  • Pour the hot water & vinegar mixture over the onions. Let the onions come to room temperature before closing the lid. This should take about an hour.
