Ingredients

The following ingredients have 8 Servings
  • 1 medium red onion
  • ½ cup hot water (it does not need to be boiling hot from the stove)
  • ½ cup apple cider vinegar
  • 1 tablespoon honey or maple syrup
  • 1 ½ teaspoons kosher salt
  • Optional flavor boosters (see above)

Instruction

  • Thinly slice the onion with a knife or mandoline, then place in a 16-ounce jar. Add any optional flavor boosters.
  • In a measuring cup, stir together the water, vinegar, honey, and salt.
  • Carefully pour the brine into the jar over the onions. Cover with a lid and refrigerate. They'll be ready to eat after about an hour in the fridge (they'll be vibrant pink), and will keep for 2 to 3 weeks in the fridge.
