(You could probably substitute chocolate syrup for the cocoa and sugar.)
Wash rice if necessary and drain. Boil gently in a covered pot with the water for 15 minutes or until rice is partially cooked. Mix sugar, cocoa and salt and add to rice. Simmer covered for 15 minutes more, stirring occasionally. When done, this will be slightly "soupy" - sort of like those nice brownie puddings. But it solidifies when refrigerated. Serve with milk, if desired. Serves 6.
