Shiso has a unique taste that is difficult to describe. It has hints of basil, cinnamon, and cumin but also possesses a bit of pepperiness and bitterness. The flavor profile may vary slightly between red and green shiso leaves. Generally speaking, the red variety tends to have a more pungent aroma than its green counterpart which is slightly more grassy in flavor. It's a versatile herb that can be used to add depth and complexity to many dishes, such as salads, sushi, sashimi, ramen, rice balls or tempura. Additionally, shiso can be used as an ingredient in sauces or pickles.
