Saigon cinnamon—a type of cassia—is like if you took the cassia cinnamon you're familiar with and concentrated it. The higher oil content makes this variety intensely fragrant and flavorful, sharp, and sweet. This is a cinnamon that stands out against other spices and won't get lost in the background. Use Saigon cinnamon in dishes when you want a stronger and spicier cinnamon profile, such as pho, curry, and other braises.
