You can eat a cinnamon stick. You just shouldn't. Instead, cinnamon sticks are both sweet and savoury and used to flavour beverages from Mexican hot chocolate, German Gluhwein and sweet, hot apple cider in North America. Cinnamon Sticks are considered to be an essential spice in the kitchen and also used in traditional Arabic, Indian and Mexican stews of lamb, goat and chicken cooked with dried fruit such as prunes or apricots.
