There are three general times when you might want to add fresh herbs to your cooking: at the beginning of the cooking process; near the end of the cooking process; or as a finishing touch. Adding fresh herbs at the beginning of the cooking process is a good way to infuse flavor into your dish from the start. Adding fresh herbs near the end of the cooking process will add a refreshing zing. Using fresh herbs as a garnish or finishing touch will add color and a fresh herbaceous aroma and flavor.
