Alabama: The Penn Burger at C.F Penn Hamburgers in Decatur
Briefly popular during the Great Depression, doughburgers were developed to get the most bang out of the limited meat people had. The Southern delicacy consists of a beef and pork mixture, plus a cheap extender like breadcrumbs or soybeans. The entire hybrid patty is then deep-fried and topped with classic toppings like onions and pickles. Although there's obviously less reason to skimp on the meat these days, the recipe lives on in select pockets of Northwest Alabama.
