Ingredients

Scale
  • 1 large red onion (about 250g), thinly sliced
  • 1/2 cup apple cider vinegar (120 ml)
  • 1/2 cup water (120 ml)
  • 1 1/2 tablespoons granulated sugar (about 20g)
  • 1 teaspoon fine sea salt (about 5g)
  • 1/2 teaspoon red pepper flakes (optional)
  • 23 black peppercorns (optional)
  • 1 clove garlic, smashed (optional)

Instructions

  1. Slice the onion: Peel the red onion, cut in half through the root end, and slice into thin half-moons about 1/8-inch thick.
  2. Place the sliced onion in a glass bowl or jar. Add any optional spices (red pepper flakes, peppercorns, garlic) if using.
  3. Make the brine: In a small saucepan, combine apple cider vinegar, water, sugar, and salt. Bring to a rolling boil over medium-high heat, about 2-3 minutes.
  4. Pour the hot brine over the onions, ensuring all slices are submerged. The onions will start to turn pink immediately.
  5. Let sit for 10-15 minutes. Stir gently after 5 minutes to ensure even pickling.
  6. Check for doneness: After 10 minutes, taste a slice. It should be slightly softened but still crunchy. Adjust time as desired.
  7. Cool and use or store: If using immediately, let cool slightly. For storage, cool to room temperature, then transfer onions and brine to a sealed jar and refrigerate.

Notes

Don’t throw away the leftover pickling liquid! It’s fantastic for adding a tangy kick to salad dressings, marinades, or even a bloody mary. For a crunchier texture, slice onions 1/8-inch thick and don’t let them sit in the hot brine for more than 15 minutes. The flavor deepens and mellows over the first few days in the fridge.
