Ingredients
  

Main Ingredients
  • 1 large red onion, thinly sliced White or yellow onions work too
  • 1 cup apple cider vinegar Or red wine vinegar for a bolder flavor
  • 1 cup water
  • 1 tablespoon sugar Can use honey or agave for different sweetness
  • 1 teaspoon salt
  • 1 clove garlic, smashed Optional
  • 1-2 slices jalapeño Adjust for heat
Optional Spices
  • cumin seeds
  • bay leaf
  • black peppercorns

Method
 

Preparation
  1. Peel the onion and slice it as thinly as possible. The thinner the slices, the quicker they pickle.
  2. In a medium saucepan, combine the apple cider vinegar, water, sugar, and salt. Heat over medium heat until the sugar dissolves.
  3. Once sugar is dissolved, remove the saucepan from heat and add the sliced onion, smashed garlic, and jalapeño slices. Stir well to coat the onions.
  4. Transfer the mixture to a clean jar, packing the onions tightly and ensuring they are submerged in the liquid. Use a small weight or parchment if necessary.
  5. Let the onions cool to room temperature before sealing the jars and refrigerating for at least an hour, preferably overnight.
