Shiso is a Japanese herb with a unique flavor: hints of citrus, mint, basil, anise, and coriander are all incorporated into its tiny leaves, which can be red or green. They are a part of the seven spices of Japan, originating from over 300 years ago in Kyoto.
Green shiso leaves are often used as a garnish for sushi and sashimi, but they are also added to soups and tempuras. Red shiso is mostly used to color umeboshi and pickled ginger. Whether red or green, shiso can be used in a variety of other dishes: mixed into salads, tossed into green tea, added to stir-fries, or chopped and prepared with scrambled eggs.
