This works well as a part of a meze-style spread of salads, or as a side for fish or chicken. The pickled onions keep in the fridge for a good week, so it’s worth making double to ensure you have plenty left over: a spoonful is a welcome addition to all sorts of salads or piled into a cheese sandwich.
Put the strips of lime skin in a medium bowl with the vinegar, onion, half a teaspoon of sugar and a quarter-teaspoon of salt. Massage the onions for a minute, until the liquid turns pink, then leave to pickle for at least two hours: the longer you leave them, the brighter and pinker they become.
