On my trip to India I'm visiting Kerala about mid way timewise and since that state is pretty famous for its spices, I'd like to know which spices are the most famous (and the best) ones which I absolutely must buy there and not elsewhere in India.
I mentioned that Kerala is mid way during my journey because I don't intend to travel across half of India with a couple of kilos of spices in my backpack and will therefore buy only certain spices in Kerala and the rest in Delhi, right before my return flight.

I understand that this question is kinda subjective but I think it can be answered since there must be some spices such as saffron that are much better there. I do cook a lot and use different spices all the time but I don't know even the hundredth of all the spices India has to offer so need some suggestions on that front.
