Although dismissed offhand as one of those ‘Southern’ frivolities—think, the much-queried ‘h’ that appends not a few ‘t’s and ‘d’s—the ‘i’ at the heart of the spelt-as-spoken biriyani is hardly superfluous.

It’s not for nothing that biriyanis regularly pip pizzas for top spot on annual consumer food-beh-aviour surveys.
