Put a clean damp (wet but not runny) cloth or paper towel on top of your rice in a microwave safe dish and heat it for 2 minutes. Don't put a lid on top of the dish.

In an oven:
Put rice in the pot with few drops of water. Cook with lid on, 300 F for 7-8 minutes.

On stove top:
Put rice in the pot with few drops of water. Cook with lid on, low heat for 5 minutes.
