Cinnamon - that most popular of spices - comes from the bark of an evergreen tree. Cinnamon's sweet, spicy and warm fragrance adds pungent sweetness to your favorite baked goodies. You can also use it to add a depth of flavor to savory dishes as well. Cinnamomum cassia (grown primarily in China and Indonesia) is reddish-brown and pungently sweet, while Cinnamomum zeylanicum (from Sri Lanka and India) is buff-colored and mild. Cassia is usually preferred for its more intense color and flavor. Korintji (thick quill cinnamon) and Batavia (thin quill cinnamon) are two types of C. cassia . Korintji comes from a higher altitude than the Batavian and has a slightly more intense reddish-brown color and sharp cinnamon flavor; it's considered the better variety. There are many species of cassia, including C. aromaticum (from China), C. burmannii (from Indonesia), and C. loureirii (from Vietnam or Saigon). True cinnamon, also known as Ceylon cinnamon, is obtained from C. verum, grown in Sri Lanka. It's tan and very mild.
