Preheat the oven at 180°C. In a large bowl combine together refined flour, cornmeal, sugar, salt, baking powder, eggs, milk, oil and sweet potatoes and sufficient water to make a soft dough.
Cover with damp cloth and let it rest for fifteen minutes.
Again knock back the dough and roll them into a loaf. Grease the bread tin and put the loaf into it and let it prove for fifteen to twenty minutes. Bake for ten to twelve minutes. Cut into slices and serve warm.
