Indonesian Cinnamon Sticks, or Cassia cinnamon sticks, are the most popular variety of whole cinnamon used with cooking and baking recipes, especially in the United States. These cinnamon sticks carry that familiar, classic cinnamon mild flavor that you're used to tasting in your baked goods and desserts. Use a whole cinnamon stick or two as a stirrer in your coffee, eggnog or hot cider. For a savory use, try using cinnamon sticks whole or grated with authentic curry recipes.
