Equipment

  • 1 Sharp knife
  • 1 Cutting board
  • 1 1 litre glass jar with tight-fitting lid
  • 1 Small saucepan

Ingredients
  

  • 2 large red onions about 500 g, root ends trimmed, sliced pole to pole
  • 1 jalapeño thinly sliced
  • 3-4 thin slices beetroot
  • 1 whole star anise
  • 1 bay leaf
  • 1 tsp mustard seeds
  • 1 tsp black pepper crushed
  • 1 tbsp fine sea salt
  • ½ cup white distilled vinegar or apple cider vinegar
  • 1 cup water

Instructions
 

  • Trim the root end off each onion completely. Slice the onions pole to pole, following the natural lines on the onion, for maximum crunch.
  • Tightly pack a clean 1-quart glass jar with the sliced onions, jalapeño slices, and beetroot slices. Add the bay leaf, mustard seeds, and crushed black pepper.
  • In a small saucepan, combine the water, vinegar, star anise, and salt. Heat on the gas until steam just starts rising, do not boil. Remove from heat.
  • Carefully pour the warm brine over the jar, covering the onions completely. Seal the lid and give the jar a gentle mix.
  • Refrigerate for at least a few hours, ideally 24 hours. Keeps up to 1 month in the refrigerator

Notes

  • Always keep the brine ratio at 1 part vinegar to 2 parts water.
  • Never boil the brine — steam means ready, bubbles mean too far.
  • Always use a clean, dry spoon and keep the jar refrigerated.
  • The brine can be reused once: reheat to steamy and pour over fresh onions.
