Pickling from scratch is not rocket science: You need a vegetable, and you need vinegar. That said, pickled radishes are especially satisfying. They sate our hunger for instant pickle gratification because they take barely 30 minutes to make from start to finish. Fresh tarragon gives the radishes a hint of anise-y flavor that infuses not only the radishes but their pickling liquid too. Uses for pickled radishes are limited only by your imagination: Slice thinly and shingle on a sandwich, chop to perk up a salad or serve as dippers alongside Green Goddess dressing. And save that pickling liquid to use in a simple, punchy vinaigrette.
