Jamie Oliver’s Instant Pickled Onion is a quick-pickled condiment made by soaking thinly sliced onions in vinegar, sugar, and salt. The onions soften within minutes and absorb a sharp, sweet, tangy flavour that enhances many dishes.
Use a sharp knife or mandoline to get very thin slices. Thin slices absorb the flavour quickly and pickle more evenly.
Combine vinegar, sugar, and salt in a bowl. Stir well until the sugar dissolves to create a balanced brine.
Place the sliced onions into the mixture, making sure they’re fully submerged for even pickling.
Allow the onions to soften and turn bright pink. The flavour intensifies as they rest.
Add lemon juice, chilli flakes, or extra sugar depending on your preferred balance of tang and sweetness.
