Hot-Pink Pearl Onion Pickles

These vibrant hot-pink pearl onion pickles are as striking to look at as they are delicious to eat. By using a small piece of beetroot in the pickling brine, the onions take on a brilliant, jewel-like magenta hue that brightens up any plate. The combination of dried tarragon, mint and coriander seeds provides a sophisticated, herbal depth that balances the sharp tang of the white wine vinegar.

This simple vegan condiment is a fantastic addition to a traditional ploughman’s lunch, colourful salads or served alongside rich savoury tarts. Making your own pickles at home is incredibly rewarding, and because these mellow over time, they are a great make-ahead option for weekend entertaining or seasonal gifting.

Ingredients for Hot-Pink Pearl Onion Pickles

  • 350ml white wine vinegar

  • 1 tablespoon sugar

  • 2 teaspoons coriander seeds

  • 2 teaspoons dried tarragon

  • 2 teaspoons kosher salt

  • 1 teaspoon dried mint

  • 230g pearl onions, peeled, halved

  • 1/2 small beet, peeled, halved

Bring vinegar, sugar, coriander seeds, tarragon, salt, and mint to a boil in a small saucepan, stirring to dissolve sugar and salt. Reduce heat to a simmer and add onions and beet. Cook, stirring occasionally, until onions soften slightly, about 3 minutes. Pluck out and discard beet (the onions will continue to take on colour as they sit). Transfer onions and brine to a 1-qt. jar or a nonreactive container and let cool. Cover and chill at least 2 hours before serving. The flavour will mellow as it sits.
