Make up approx. 700ml of chicken stock with 1 stock cube. Add a ladle or two of stock to the pan and stir well. Lower the heat and let the stock be absorbed into the rice. Stir the risotto regularly, and gradually add the stock 1 ladle at a time allowing each to be absorbed until the rice is cooked. You may not need all the stock - I use about 650ml. If you need a little more, hot water can be added.
