Cook Time:2 hours
Total Time:2 hours 10 minutes

Ingredients
 

  • 1 large red onion
  • 1/2 cup water
  • 1/4 cup apple cider vinegar
  • 1/4 cup white vinegar
  • 1 1/2 tablespoons sugar
  • 1 teaspoon salt
  • Optional: small pinch of red pepper flakes

Instructions
 

  1. On a cutting board, trim off both ends of the onion and discard the outer skin. Cut in half from top to bottom. Lay both halves flat side down and then slice very thinly vertically (from top to bottom). (Alternatively, you can use a mandolin to slice the onions.)
  2. Pack the onions down into a 16-ounce jar.
  3. In a small pot, add the water, both vinegars, sugar, salt, and (optional) red pepper flakes. Bring to a boil and then remove from the heat.
  4. Pour this brining mixture over the onions, screw on the lid, and place in the refrigerator for at least 2 hours. These taste best if eaten within about 3 days, but can remain in the fridge for 2-3 weeks.

Notes/Tips
