Santiago's longaniza recipe is said to trace back to Spanish settlers in the Cibao Valley, and the citrus-and-oregano seasoning blend is still guarded family-to-family among the city's longaniza stands.
A garlicky, bitter-orange-marinated pork sausage grilled over charcoal and sold from roadside fritura carts and colmados across Santiago, usually sliced into a roll with fried onions and ketchup or mustard.
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.
