Somoto's bakers still fire their clay ovens with wood, a method locals say is what keeps the rosquilla's crunch different from versions baked anywhere else in the country.
Corn flour is kneaded with aged cuajada cheese and eggs, shaped into small rings, and baked hard in a wood-fired clay oven until crisp. Roadside stands along the highway through Somoto sell them by the bagful to passing traffic.
