What specialized storage method avoids direct contact with cold, moist plastic to maintain arugula's crispness?

Wrapping the leaves loosely in a dry paper towel inside a slightly open plastic bag

Proper storage is key to extending the freshness of delicate leafy greens like arugula, and the text provides a specific technique to combat moisture damage. The critical recommendation is to never store the leaves directly against the cold, moist environment of the refrigerator drawer plastic. Instead, one should wrap the leaves loosely using a dry paper towel. This wrapped bundle should then be placed into a plastic bag that is left slightly open, or into a loosely closed container. This barrier manages the excess moisture, which is identified as the primary enemy of crispness, allowing the leaves to stay cool but preventing them from becoming soggy, thus extending their vibrant state by several days.
