The Differences Between Natural Spices and Fakes ones

Chinese cassia is often sold instead of cinnamon. They look alike, but cassia has a weaker aroma. In addition, cassia sticks are thicker and more coarse, and they’re curled mainly to one side. Ground cinnamon can be easily distinguished from cassia by adding a drop of iodine into the powder. If the spice turns blue, it’s cassia.
