Dominican longaniza is usually coiled and fried rather than grilled, and a plate of it with tostones is a standard order at any fritura stand.
A garlicky pork sausage seasoned with bitter orange and oregano, fried until crisp in its own fat and sold from fritura stands and colmados across Santiago, usually cut into pieces and served with tostones or fried yuca.
Why it's made this way: Santiago sits at the heart of the Cibao Valley, the country's pork- and produce-rich agricultural core, making it the city most closely identified nationwide as the sausage's origin and best source.
