☞ In the case of cinnamon cassia , the outer bark is torn away, and the inner bark curls in on itself, and resembles a chocolate stick. The difference is that, true cinnamon has a single spiral curl, while cinnamon cassia has a double curl.
☞ The inner bark is dried completely for 4 to 6 hours. Once dry, the bark is cut into 5 - 10 cm strips.
