The Cochinita Pibil is not spicy, but it has a uniquely sweet, earthy aroma imparted by bitter Seville oranges, achiote, charred garlic, and a host of other spices. That earthiness is normally backed with the herbaceous aroma of the banana leaves it's cooked in, along with smokiness from hours of slow cooking in a smoky, steamy píib (or, in modern Mexican Spanish, pib), the Mayan oven consisting of a hole in the ground lined with hot stones.
