Put the rice, milk, 200ml of water, half the maple syrup or honey and the vanilla into a large pan. Give it a good stir, then place the pan on a very low heat. Cook gently for around 45 minutes, or until thick and creamy, stirring regularly. Loosen the rice pudding with an extra splash of milk before serving, if needed. Peel and slice the banana, then serve the rice pudding scattered with the blueberries and banana and the remaining maple syrup or honey drizzled on top
