Ingredients

The following ingredients have 4 Servings
  • 1 medium red onion (peeled and sliced into rings)
  • 1 tablespoon sugar
  • 1/2 tablespoon kosher salt
  • 1/2 teaspoon whole peppercorns
  • 3/4-1 cup white vinegar (plus more if needed)
  • 3/4-1 cup boiling water (plus more if needed)

Instruction

  • Add the sliced red onions to a 2-3 cup jar. If it's a tight fit, just use a wooden spoon to smush them down into the jar.
  • Add the sugar (1 tablespoon), kosher salt (1/2 tablespoon), and peppercorns (1/2 teaspoon) to the jar.
  • Pour white vinegar (3/4 to 1 cup) on top of the onions, stopping when you get halfway up the jar.
  • Pour boiling water (3/4 to 1 cup) into the jar. I like to microwave water in my pyrex measuring cup until it's boiling (about 1.5 minutes) and then pour it from there, but you can use a kettle or pot on the stovetop, too.
  • Cover the jar and shake until the sugar and salt are dissolved.
  • Refrigerate for about 30 minutes, or until they're cooled off. The taste will get better the longer they sit.
