Another way to preserve fresh herbs is to store them in your freezer. Hard herbs, such as rosemary and thyme, can simply be rinsed and popped in a zipper bag for freezing. Herbs with soft leaves, like basil and cilantro, fare a little better when they're chopped up and frozen in ice cube trays filled with water. When you're ready to use them, just add them to your cooking as you would any fresh herbs. Be sure to label your frozen herbs well because they look a lot alike when frozen and don't have a distinct smell until they've thawed.
