My sincere thanks to all who attended the master-class at Zaal for their dedication in making the results of their research available to all. It is certainly an eye-opener to learn of the degree of singeing that Az aims for when he first fries his spices -- this was something that I used to do by accident in the bad old days (before I learned of the central role of the base gravy) and the results were invariably inedible. It is, unfortunately, very unlikely that I shall ever get the opportunity to try this for myself, as SWMBO would either murder me or divorce me if (as she would put it) "the house stunk of burned spices for over a week" ...
