Korean Mint is the best of two worlds- mint and licorice- combined in one.  The wonderful flavor is great in tea but these versatile leaves can also be chopped and mixed into your salad to give it a slightly sweet flavor.  In Korea, it is used for several traditional dishes such as the Korean Pancake and various stews.  It would also be wonderful, muddled into a mixed drink or added to lemonade.  So, give it a try.  The uses are only limited by your imagination.
