I think we have two different things in front of us Livo. Polar opposites. I wonder if it's the timber. Are you sure you are using cassia? The picture you posted earlier of your spices doesn't make it clear to me. It looks a bit iffy. What is it exactly?

Most definitely 100% positive Cassia Bark. My old stock, used in my first batch of gravy, came from Udaya Indian Grocery, Wentworthville, Sydney, and the bag was labelled Cassia bark. Wentworthville is the centre of the most densely Indian populated area in Australia.
The small bag I photographed is labelled cinnamon but it is Cassia Bark for sure. The guy at Namaste Indian Grocer (local) tried to sell me round cinnamon quills but I told him I wanted flat Cassia bark. He fossicked around the shelves and produced that bag. It does also have the botanical name of the tree on it which I'll report later.
Both bags, as with most Indian spices, were imported from India.
I have just made another half batch last night. Don't get me wrong. I like it, but it just needs more than cooking on its own, with just raw chicken anyway. I can see how spiced pre-cooked lamb or prawns would work better than chicken. Spiced pre-cooked chicken will be the next thing to try.
Edit: Correction.
The new bag I bought just the other day, after being very specific in what I wanted with the little Indian boy who served me, is in fact Cinnamomum Zeylanicum, or Ceylon Cinnamon. It is not in the usual quill form but more resembles small Cassia bark pieces. I've never seen Ceylon cinnamon in this form before and I already have plenty of Cinnamon quills. I didn't use it last night. I just again used the broken up small pieces left in my container of proper Cassia Bark (which was the real deal). I will now be on the hunt for some more proper Cassia Bark.
There is no doubt that the bark I have used so far is Cassia. Had I used Ceylon Cinnamon in that quantity, I would certainly have been able to tell. Whether it's freshness is an issue remains undecided.
