I recently bought some ceylon cinnamon, because one of Mom’s books said it had the highest level of medicinal compounds.
Turns out, it also has 2-3X as much flavor! I’ve had to cut back the amount I use in my pumpkin pies to 3/4tsp vs 1 tsp.
It’s the best stuff, IMHO. I use nothing else when it comes to Cinnamony Goodness. :)
