Chochoca
Chochoca (or chochoyeco, trotroyeco, trutru) is a Chilean festival dish that originated in Chile. It's made of a potato-and-flour dough wrapped around a metal cylinder shaped like a large rolling pin. The cylinder, like a roast pig, is slowly rotated for about thirty minutes to roast the dough over hot charcoal.
When the chochoca is cooked, it is sliced into pieces and eaten on its own or with chicharrones. As you might expect, it's not something you'd make at home, but rather something reserved for special occasions like fiestas and food fairs. Depending on the type of dough used, there are two kinds of chochoca: black chochoca and white chochoca.
The more traditional of the two is black chochoca, which is made with grated raw potatoes mixed with ground cooked potatoes, salt, and lard. The white version, which is more popular, is made with equal parts wheat flour and ground cooked potatoes.
