Ingredients:

  • 1 medium red onion (approx. 8 oz / 225g), thinly sliced into half-moons
  • 1 cup (240ml) apple cider vinegar
  • ½ cup (120ml) filtered water
  • 1 tbsp (18g) sea salt
  • ⅓ cup (115g) honey
  • 1 tsp (2g) red pepper flakes
  • ½ tsp (1g) cayenne pepper

Instructions:

  1. Slice the red onion into half moons about 1/8 inch thick. Note: Uniform slices ensure they pickle at the same rate
  2. Pack the sliced onions tightly into your glass jar.
  3. Pour 240ml apple cider vinegar, 120ml water, 115g honey, 18g salt, 2g red pepper flakes, and 1g cayenne into a saucepan.
  4. Set heat to medium and stir constantly.
  5. Simmer the liquid for about 5 minutes until the honey and salt disappear and it bubbles gently.
  6. Pour the hot brine directly over the onions. Make sure they are fully covered.
  7. Seal the lid immediately. Note: This traps the steam to help the onions soften slightly
  8. Leave the jar on the counter for 30 minutes.
  9. Move the jar to the fridge for at least 2 hours.
