Have you heard about cinnamon/"kayu manis"? I have read The Borneo Post dated 5th March 2009 that cinnamon will be planted at Ba`Kelalan.
Some of the community get used to mix the cinnamon powder or its bark with the coffee. I have tried it before..the smell is really nice. You have to boil the water with the cinnamon powder and then poured it into coffee. Add some sugar. The aroma combination is good enough to make your day great!
I have some pictures of cinnamon powder to share with you :

Enjoy!
