If I had to draw a Parsi food pyramid, it would rise out of a plinth of potato chips. In Bombay a potato chip, usually described as a finger chip, is what Americans know as a French fry. American potato chips are known as wafers in Bombay, in both English and Gujarati. Parsis take wafers seriously. They’re the first thing put onto the banana leaf for wedding and initiation banquets. There are several businesses dedicated to nothing but wafer production, where a vat of hot oil never sleeps.
