It's the groundnuts, not the yam, that mark this dish as distinctly northern — peanut farming is concentrated in Ivory Coast's savanna belt, from Korhogo east to Bondoukou.
Pounded yam foutou is served with a rich, ground-peanut stew simmered with tomato, onion and chili until thick and glossy. It's a staple across Ivory Coast's northern savanna towns, where groundnuts are a major local crop.
