Shiso leaf, also known as perilla, is a herb belonging to the mint family and is extensively used in Japanese, Korean, and Southeast Asian cuisine. The leaf is broad and rounded with a slightly jagged edge, and it can vary in color from green to a deep purple depending on the variety.
The scent profile of shiso leaf is unique and complex. It has a fresh, aromatic quality with notes reminiscent of mint, basil, and cilantro. Some people also detect hints of anise and cinnamon. The green variety tends to have a sharper, more peppery flavor, whereas the purple variety is slightly sweeter and milder. Shiso leaves are often used to add a bright, herbaceous component to dishes such as sushi, salads, and grilled meats. In addition to its culinary uses, shiso is also noted for its essential oils, which are used in various aromatic products for their refreshing and subtly spicy fragrance.
