To start, I grab my favorite type of onion, red, white, or yellow, and slice it into thin, even rounds. I always find this process soothing and gratifying. Next, I boil water in a kettle. While that’s heating up, I create a flavorful bath for my onions by mixing vinegar—usually apple cider or red wine vinegar—with a pinch of salt and sugar. I love how the sugar just takes the edge off the sharpness, making everything blend perfectly.

I then place my onion slices in a sieve or colander and pour the just-boiled water over them. It’s like a quick spa for the onions, softening them slightly so they’ll pickle even better. Once drained, I pack the onions into a clean jar, pouring in my vinegar mix until the onions are completely covered. I take a moment to stir around with a blunt stick to chase away those pesky air bubbles that could spoil the pickling process.

Finally, with my onions fully submerged, I seal the jar and pop it into the fridge. The wait is the hardest part for me. But in just a few hours, I get to enjoy my quick pickled onions, adding a zesty crunch to salads, sandwiches, or tacos. Plus, it’s a relief knowing that I’ve saved money and prevented waste by preserving these onions before they could go bad.
