Equipment

Ingredients
 

  • 1 large red onion
  • 240 ml (1 cup) water
  • 240 ml (1 cup) apple cider vinegar or white/ white wine vinegar
  • 50 grams (¼ cup) raw cane sugar
  • 1 teaspoon salt
  • 1 teaspoon whole peppercorns
  • 4 star anise

Instructions
 

  • Measure the water, vinegar, and sugar into a saucepan and add a generous pinch of salt.
  • Bring the pickling solution to a boil, stirring to allow the sugar to dissolve.
  • Finely dice the red onions into thin strips and place them into prepared sterilized jars.
  • Pour the hot pickling liquid over the red onions. Make sure the onions are completely covered but that there is still around a finger width margin of space at the top of the jars.
  • Let the pickled onions cool before screwing on the lids and placing them in the fridge. Leave them overnight and then consume within 2 weeks.

Notes

The pickled red onions can be enjoyed after a couple of hours if sliced thinly enough, but are best left overnight.
