  • 1 cup (115g) red onion (1 medium, very thinly sliced
  • 1/2 cup (118 ml) water
  • 1/4 cup (59 ml) distilled white vinegar
  • 1/4 cup (59 ml) apple cider vinegar
  • 1 1/2 tbsp. (22 ml) pure maple syrup
  • 1 1/2 tsp. sea salt


  1. To make the quick pickled onions, press the sliced onions into a 1-pint (473 ml mason jar) or similar heat-safe container. Place the jar in the sink, as this will help to catch any splashes of hot vinegar later.

  2. In a small saucepan, combine the water, white vinegar, apple cider vinegar, pure maple syrup, and sea salt. Bring the mixture to a gentle simmer over medium heat, then carefully pour the heated mixture into the jar over the onions.

  3. Use a spoon to press the onions down into the vinegar and remove any air bubbles in the jar.
  4. Let the pickled onions cool to room temperature, about 25-30 minutes before serving.
