How to moisten a dry prosciutto leg?

To moisten a dry prosciutto leg, you can lightly brush it with a small amount of water or a mixture of water and olive oil. Wrap it in a damp cloth or cheesecloth to help retain moisture. Alternatively, placing it in a humid environment, such as a sealed container with a small bowl of water, can also help restore some moisture over time. Avoid soaking it, as that can affect the flavor and texture.
