Pounding foutou by hand traditionally takes two people working in rhythm — one turning the paste in the mortar, one striking it with the pestle — which is what gives it its stretchy, dumpling-like texture.
Boiled plantain, sometimes mixed with cassava or yam, is pounded into a smooth, elastic paste and served with a deep-purple eggplant sauce cooked down with tomato, onion, chili and meat or fish. It's eaten by hand in small torn pieces, dipped straight into the sauce.
