To extend the life of fresh berries, put the unwashed berries in a glass jar, with the lid on, and pop them in the fridge. It works beautifully on strawberries; they’ll keep their fresh-from-the-farm taste for about two weeks. Blueberries, blackberries, and raspberries, which tend to be delicate and perishable, keep just as well this way; grapes may last even longer. Mushrooms, and jalapeno and serrano chiles benefit from the treatment, too. If your cherry tomatoes get to the point where they have to be refrigerated, the jar method will extend their a life a little more. Herbs seem to do quite well too. Wash them, blot them dry to prevent mold, and place them loosely in the jar.
