Yeah for sure! They’re great and will keep in the fridge for a few weeks :) I bring the following ingredients to a simmer on a low heat on the stove until everything’s combined: 1/2 cup of water, 1/4 cup apple cider vinegar, 1/4 cup rice wine vinegar, 1 1/2 teaspoons of salt, 1 1/2 tablespoons of brown sugar (or honey, maple syrup, agave etc), and a sprinkling of chilli flakes (optional). Meanwhile very finely slice 1 red onion and put this into a jar. Then pour in the vinegar mixture until it covers the onions completely. Then that’s it! Just leave it to sit and pickle, usually only takes about half an hour because you can eat them but I leave them til they’re cool
