One single-village version, Manapparai murukku, became so prized that Tamil Nadu's government applied for a geographical-indication tag for it in 2010 — a legal protection ordinarily reserved for wines and cheeses, applied to a roadside fried snack.
Rice flour and urad dal flour are kneaded with cumin or sesame seeds, chili powder, and asafoetida into a stiff dough, pressed through a disc-shaped mold into tight spirals, and deep-fried until crisp. Tea stalls, snack shops, and Diwali stockpiles across Tamil Nadu keep it on hand as an anytime crunchy snack.
