What I have noticed, Edwin, in my recent BIR journey, is that fenugreek, in either or both of it's forms, is the big difference between BIR and traditional Indian cuisine.
Fenugreek, as a flavour-enhancer seems to be used in virtually every BIR dish I have come across, either in the base or final dish.
If you want to use it, in leaf form, is entirely your decision....what's right for me may not be right for you, and vica versa. I can only suggest that you try it; and if you like it, keep doing it ;D
