I am making cinnamon tea as it is claimed the spice helps diabetes. Steep one tsp of cinnamon in boiling water for 10 minutes. Add an ordinary tea bag for three minutes and then tsp of unprocessed honey. Will see if it helps in any way. Make sure the cinnamon is Ceylon type not cassia.
I think I would drink it unsweetened, or use a less carby sweetener than honey. My preference would be xylitol or erythritol.
I also had the most fabulous cinnamon toast, once (centuries ago) which was basically a blend of cinnamon, butter and brown sugar, spread on fabulous granary bread.
Nowadays, I would use butter, cinnamon and erythritol, in approx equal quantities, on LivLife toast.
Yum!
