Before refrigeration reached rural Antioquia, families fried whole pig bellies down to chicharrón and stored the pieces submerged in their own rendered fat, a preservation trick that could keep pork edible for weeks.
Squares of pork belly are fried low and slow until the fat turns brittle-crisp and the meat underneath stays tender, then piled hot onto a paper plate or banana leaf at street-side fritanga carts. Vendors sell it by weight straight off a sizzling griddle, usually alongside arepa and avocado.
