ingredients

  • 1 cup water
  • 1 cup apple cider vinegar (or white vinegar)
  • 2 tablespoons sugar
  • 1 tablespoon kosher salt
  • 2–3 cups red onions, thinly sliced
  • 2–3 garlic cloves, thinly sliced
  • 1 jalapeño, thinly sliced
  • 2 bay leaves
  • 15 black peppercorns

Method

  • Step 1

    In a small saucepan, combine the water, vinegar, sugar, and salt. Bring to a simmer over medium heat, stirring to dissolve the sugar and salt.

  • Step 2

    In a large, clean mason jar, layer the sliced red onions, jalapeño, garlic, bay leaves, and peppercorns.

  • Step 3

    Carefully pour the hot vinegar mixture over the onions and aromatics, ensuring everything is fully submerged. Use a spoon to press down any floating ingredients if needed.

  • Step 4

    Let the jar cool at room temperature, then seal with a lid and refrigerate. The pickles will be flavorful within a few hours, but best after at least 24 hours. Keep refrigerated for up to 2 weeks.
