If you cannot find Scotch Bonnet peppers where you are substitute Habanero pepper instead. The bland aspect may be due to the hot peppers you are subbing in? Scotch Bonnet are hot AND flavourful too.
Based on some reviews I added more Thyme as well and I used more than the required Medium Curry powder I had in the cupboard. I will head to the Caribbean store and get their curry powder for next time!
fantastic flavour ! I'm not going to lie-my first time actually finding and using a Scotch Bonnet-I made it too hot ~
