Ingredients

  • 2 small red onions
  • 2 cupwhite vinegar
  • 2 cupwater
  • cupcane sugar
  • 2 tbspsea salt
  • 2 garlic cloves, peeled(optional)
  • 1 tspmixed peppercorns, whole(optional)

Instructions

  1. Slice the onions into thin half-moons — aim for about 1/8-inch thick so they pickle evenly. Pack them into 2 (16-oz) jars or 3 (10-oz) jars, tucking the garlic cloves and peppercorns between the layers if you're using them.
  2. Combine the vinegar, water, sugar, and salt in a medium saucepan and bring to a simmer over medium heat. Stir occasionally until the sugar and salt completely dissolve — you'll know it's ready when the liquid looks clear.

  3. Allow the hot brine to cool for a few minutes, then pour it over the onions, making sure they're completely submerged. Let everything cool to room temperature before transferring to the refrigerator.
  4. The onions need at least 1 hour to transform into their bright pink, tender selves — though overnight is even better if you sliced them thick. They'll keep their punch for up to 2 weeks in the fridge.
