Do not assume that if your quills are round rolls, like cinnamon quills, they are cinnamon, ie; True or Ceylon Cinnamon.
Agreed. As far as I am concerned, the most obvious characteristic that one should look for when attempting to purchase true cinnamon is the delicacy of the bark that constitutes the quill — true cinnamon will have very delicate bark, almost like parchment; cassia will have coarse bark, 1/16" thick or more.
