Ingredients

  • 1 large red onion
  • ½ cup white vinegar
  • ¼ cup water
  • 1 teaspoon sea salt
  • ½ teaspoon granulated sugar
  • 1 Bay leaf

Instructions

  • Start by cutting off both ends of your red onion. Slice it in half and each half into half-circle, thin slices. Set aside.
  • In a 1-quart saucepan, mix vinegar, water, salt and sugar. Bring to a boil.
  • Add onion slices to the saucepan and simmer for 3 minutes. Stri often. At first you may need to press down on the onions to submerge them in the liquid.
  • After 3 minutes, remove the saucepan from heat and pour onions and liquid into a heat-proof bowl or cup. I used a 4-cup Pyrex glass measuring cup.
  • Add 3 ice cubes to cool the mixture down.
  • Place onions and liquid into a jar and cool completely before storing in the fridge.

Notes

  • Store your pickled red onions in a glass jar with a lid, in the fridge, and they will last up to 3 weeks
  • You can also add peppercorns, garlic, and mustard seeds to the mixture.
  • You can use white or yellow onions as well in this recipe.
