1. Start to cook your rice as per the recommended method indicated on the packaging
2. When you think your rice is cooked, remove a few rice kernels from the pot and place them in the middle of a 10 x 7cm square of tinfoil or wax paper
3. Fold over the tinfoil/wax paper, so that the rice kernels are covered
4. Using the back of either a wooden/dessert spoon press down firmly on the rice kernels
5. Open the folded part of tinfoil/wax paper
6. If any hard opaque areas are present in the flattened rice kernels, the rice still needs to be cooked some more
7. Continue with this process (you can use the same square of tinfoil/wax paper until you run out of space) until no white hard cores are visible in the flattened rice kernels any more, your rice is then cooked.
