These bracing carrot ribbons are sweet and tart and deliciously peppery. Ginger works as a seasoning here, and it becomes part of the pickle. Both mature ginger and young ginger work well in this recipe. When the latter is available, this is a nice place to try it; you’ll get a zippy brightness with a more mellow heat. These pickles are perfect for packing onto sandwiches, and they make great companions for cheeses and salads. Use medium-size carrots and a nice sharp vegetable peeler for quick and easy ribboning.
