Article:
Pour a small amount of salt on a plate, then press the fleshy part of the lemon or lime into the salt. Apply a thin layer of salt over the fruit flesh. Leave some salt on the plate so you can dip the fruit in more salt as needed. Hold the copper item under a stream of warm water until you don't see anymore fruit flesh or salt. Turn the item over in your hands as you rinse it so that it's thoroughly cleaned.
