I saw my folks recently who have just came back from India. They brought with them a big bag of this cinnamon bark which I am working my way through. If you nibble a bit it tastes just like that American gum brand, Big Red, quite peppery! It’s great to add flavour when stewing, poaching and boiling. I think you can get similar bark in little deli shops and things- I’ve spied it in a good Turkish one near me.
