The Method for Pickled Onions

Tap a step to highlight it, or turn on Cook Mode for large type and step-by-step focus.

  1. Cover the unpeeled onions with boiling water for 30 seconds, drain, and the skins will slip off easily. Trim the roots as little as possible.

  2. Layer the peeled onions in a bowl with the salt, cover, and leave 12 hours.

  3. Meanwhile, bring the vinegar, sugar and all the spices to a simmer for 10 minutes, then take it off the heat and leave it to go completely cold.

  4. Rinse the onions thoroughly under cold water and dry them well on a cloth.

  5. Pack them tightly into sterilised jars with a bay leaf and a chilli in each.

  6. Pour the cold spiced vinegar over, including the spices, until the onions are completely covered.

  7. Seal and leave six weeks in the fridge before opening.

Things to Watch For

  1. Dry salt, never a wet brine. Wet brine gives soft onions.
  2. Cold vinegar over. Hot vinegar makes them slippery.
  3. Six weeks minimum. They are harsh before that.

Good to Know About Pickled Onions

Brine dry, in salt, overnight — not in a wet brine. Salt on its own pulls water out of the onion by osmosis and leaves the layers firm, while a wet brine soaks water back in and gives you soft pickled onions, which are a waste of six weeks. The vinegar must be cold when it goes over: hot vinegar cooks the outer layers and they go slippery. Peel them under water or in a bowl of iced water if you would rather not weep through the whole job.

Storing Leftovers

Sealed in the fridge for 12 months, and in the fridge after opening. Raw onions in cold vinegar are not heat-processed, and jars for the cupboard need a tested recipe and processing in a boiling-water canner.
