Their crisp texture, vibrant colour and peppery flavour makes radishes a popular addition to salads. Choose radishes that feel firm and smooth. Once opened, store wrapped in kitchen paper in the fridge. To refresh radishes that have become soft, soak in a bowl of cold water for a couple of hours. Roast radishes with thyme and dunk in a blue cheese dip, or slice thinly to add peppery crunch to a trout, orange and pomegranate salad.
