Similar in appearance to spinach, sorrel is a bright, fruity, and tart spring green. While it?s often wilted and mixed into soups, purées, and sauces, sorrel can also be added to risottos, gratins, and omelets. For the more inventive cook, sorrel can even be added to dessert recipes, where its exuberant lemon flavor lends balance to otherwise saccharine flavor profiles.
