Once the rice has boiled drain, and add 3 1/2 cups of the Milk stir and simmer for 15 minutes but you need to keep stirring, so that the rice does not stick. Dissolve the Corn Flour into the 1/2 cup of Milk thats left over and add into the sauce pan along with the Sugar. Stir and continue to boil for at least 10 minutes until thick.
