Ingredients
  

Main Ingredients
  • 2 medium red onions
  • 1 cup apple cider vinegar
  • 1 cup water
  • 1 tablespoon sugar
  • 1 teaspoon salt
  • 1 teaspoon peppercorns
  • 2 garlic cloves sliced

Equipment

  • Mandoline or sharp knife
  • Heat-proof Mason jar
  • Saucepan

Method
 

Preparation
  1. Thinly slice the red onions using a mandoline or a sharp knife.
  2. Pack the sliced onions into a clean, heat-proof Mason jar.
Brine
  1. In a saucepan, combine apple cider vinegar, water, sugar, salt, peppercorns, and sliced garlic cloves.
  2. Bring the mixture to a boil, then immediately remove from heat.
Pickling
  1. Carefully pour the hot brine over the onions in the Mason jar, ensuring they are fully submerged.
  2. Seal the jar and let it cool to room temperature.
  3. Once cooled, refrigerate for at least 30 minutes before serving, though they are best after 24 hours and will keep for up to 2-3 weeks.

Notes

For extra flavor, you can add a sprig of fresh dill or a bay leaf to the jar with the onions before pouring in the brine. Adjust sugar and salt to your taste. The onions will become more flavorful the longer they sit in the brine.
