Equipment

  • Mandoline or sharp knife
  • 12 ounce mason jar with lid

Ingredients
  

  • 1 small red onion (about 6 ounces peeled and thinly sliced)
  • ½ cup (4 ounces) apple cider vinegar
  • ½ cup (4 ounces) water
  • 1 tablespoon granulated sugar
  • ½ teaspoon Kosher salt

Instructions
 

  • In a microwave-safe measuring cup, combine vinegar, water, sugar, and salt. Heat in the microwave on high until hot and the sugar/salt dissolves (about 60 to 90 seconds). Whisk to combine.
  • Trim both ends of the onion, leaving the root end intact. Peel the onion and slice it in half from the stem end to the root end. Use a mandoline (2 mm blade) or knife to thinly slice the onion. (See Tip 1)
  • Add sliced onions to a 12-ounce mason jar. Pour hot brine over the onions until fully submerged. (See Tip 2)
  • Let cool to room temperature. Seal and refrigerate for at least 30 minutes before using.
  • Yield: 8 to 10 servings.

Tips/Notes

  1. I ended up with about 1 ¼ cups of thinly sliced onions.
  2. Although the 12-ounce jar holds just 1½ cups, the onions compress and the brine fills the gaps. Using 1 cup of liquid is just right. There is no overflow and no waste.
