Shiso is a well-loved in Japan, where it is considered one of the dento yasai, or culturally important traditional vegetables. The leaves have a texture similar to mint, and a complex, citrusy flavor with hints of spice. In Japan, whole leaves of green shiso accompany sushi and sashimi, and chopped leaves flavor many other dishes. In the US, the herb has recently gained attention of mixologists for use in drinks, and chefs creatively using its unique flavor in desserts. It can add a little twist to just about any dish where you would usually use basil or mint.
