For the infrequent cook in your life (who may be yourself), the Prepara Herb-Savor keeps herbs fresh in your refrigerator for three weeks. The stems are kept in water inside the storage device, which fits inside standard refrigerator doors. It's also good for keeping asparagas fresh for a longer period of time, which is great if you live alone and can't eat a whole package of asparagas in one sitting.
