Vietnamese Cinnamon Spicy and sweet, this cinnamon is top shelf and a step above your regular brand. It has some distinctive characteristics that set it apart from the other cinnamon varieties. Its high volatile oil content makes the bark extremely potent. Vietnamese cinnamon is fiery, rich, fragrant, and a favorite with many pastry chefs. It will change how you look at cinnamon. My favorite, a splash in my pot of Midwest chili. (seriously)
