Elsewhere in Madagascar the same soupy rice is called vary sosoa, and it's cooked with several times more water than an ordinary pot of rice, turning it almost creamy.
Rice is simmered in far more water than usual until it breaks down into a soft, soupy porridge, then served with grilled meat skewers, pickled vegetables, fried or salted fish, or an omelet on the side.
