Pickled red onions

Pickled onions

These are one of our most-used “little extras” in a busy kitchen because they’re quick to make, easy to scale, and they lift whatever you’re serving. Salads, burgers, wraps…if you can make a good pickle, it elevates the whole plate.

Makes

Approx. 1-1.2 litres pickled onions. Yield depends on how tightly you pack the jar.

Prep time

10 minutes (plus optional 30 minutes salting)

Ready in

About 3 hours if you’re in a hurry, but best overnight. Give it a week and it goes to another level.

Ingredients

Onions

Optional (for a slightly better pickle):

Pickling liquid

Flavour options (choose what you like)

Method

  1. (Optional) Salt the onions

    If you’ve got time, toss the sliced onions with 10g salt and leave for 30 minutes, then give them a quick rinse and drain well. This step is optional.

  2. Pack the jar

    Put the sliced onions into a clean jar (or any container). Thin slices are perfect for salads; thicker slices give more bite.

  3. Make the pickling liquid

    Add the sugar and vinegar to a pan (and water if using).
    Add your chosen aromats (star anise, cinnamon, chilli etc).
    Warm gently, stirring until the sugar has dissolved (no need to aggressively boil – you just want everything dissolved).

  4. Pour, seal, chill

    Pour the warm pickling liquid over the onions, seal the jar, and refrigerate. It’s usable in 3 hours if you’re in a rush, but it’s best overnight.

How to use

Storage

BM’s guidance for quick pickles is up to 4 weeks in the fridge, and the brine itself will keep around a month if stored cleanly.
