Dégué came to Ivory Coast from neighboring Mali and Burkina Faso, where the same millet-and-sour-milk dessert is sold chilled in small plastic bags by street vendors.
Steamed fonio or millet grains are folded into sweetened, slightly sour curdled milk, served chilled as a snack or light dessert. It's a common sight at markets and after-school stalls across Ivory Coast's northern towns.
