How to choose: Fresh arugula has long, bright green leaves. Buy it with the roots intact if you can.
How to store: Wrap the stems of arugula with roots in a moistened paper towel and place in a plastic bag. Keep loose leaves in a plastic bag. Refrigerate both types up to 3 days. Follow the expiration date for packaged arugula.
Best uses: Arugula tends to be gritty, so rinse the leaves thoroughly. The greens can be stirred into pasta, scattered on pizza, and, of course, used in salads.
