Cost: $2.04 total, $0.51 per serving

Ingredients

  • 2 medium Red Onion (peeled and sliced thin with the grain)
  • 1 cup White Distilled Vinegar (for the pickling brine)
  • 1 cup Water (room temperature)
  • 1 tablespoon Granulated Sugar (helps balance acidity)
  • 1 tablespoon Salt (regular table salt or kosher salt)

Instructions

  1. Prepare the onions

    Peel the two red onions and slice them thinly, cutting with the grain (parallel to the layers) to keep them crisp.

    Time: PT5M

  2. Pack the onions

    Place the sliced onions into a clean glass jar or deli container, pressing them down with a spoon or fork so they fit tightly.

    Time: PT2M

  3. Make the pickling brine

    In a small saucepan combine 1 cup vinegar, 1 cup water, 1 tablespoon sugar, and 1 tablespoon salt. Bring to a gentle simmer, stirring until the sugar and salt are fully dissolved.

    Time: PT5M

    Temperature: simmer

  4. Add brine to the onions

    Remove the saucepan from heat. While the brine is still warm, pour it over the onions in the jar, ensuring they are completely submerged. Press the onions down with a spoon or fork, then seal the lid tightly.

    Time: PT2M

  5. Refrigerate

    Place the sealed jar in the refrigerator for at least 2 hours before using. The onions will become tangy and slightly softened while retaining a nice crunch.
