In the northern hemisphere, it's getting warmer, so local farmers' markets are beginning to overflow with early Spring produce: artichokes, asparagus, and green garlic.
Don't be afraid to stock up on fresh fruits and vegetables for fear that they might go bad before you get to use them. Most produce will stay fresh for up to one whole week if you store them properly. One of the websites for the southern California farmers' markets, FarmerNet, has a great little list of how to properly store your fruits and vegetables for maximum freshness. For example, don't wash berries until right before you plan to use them, keep tomatoes uncovered at room temperature, and cabbage and celery will keep for two weeks in the refrigerator.
