Across West Africa the same dessert goes by other names — dégué in Mali and Burkina Faso, chakery in Nigeria — and in Senegal it's usually made with arraw, tiny rolled millet granules.
Tiny steamed balls of millet semolina are mixed with sweetened curdled milk or yogurt, vanilla, and sometimes raisins or grated coconut, then chilled into a tangy, creamy dessert. It's sold by the cup from coolers at markets and served in heaping bowls at baptisms and weddings.
