Cinnamon basil, also known as Mexican spice basil, has a spicy, fragrant aroma and flavor. It contains methyl cinnamate, giving it a flavor reminiscent of cinnamon. Cinnamon basil has somewhat narrow, slightly serrated, dark green, shiny leaves with reddish-purple veins, which can resemble certain types of mint, and produces small, pink flowers. Cinnamon basil is used in teas and baked goods such as cookies and pies. It is also used in pastas, salads, jellies, and vinegars.
