1. Check if your rice sinks in water. Put a tablespoon of rice in a glass of water. If your rice floats, you have got the fake stuff.
2. Do not eat the rice if you notice a thick layer on the surface when you boil it.
3. The fungus test can give you a hand on this one. Cook a cup of rice, transfer it in a container, and leave it on your counter. Check your rice in a few days. If you see mold, the rice is organic and all-natural. If it still has no mold, you have just cooked a cup of plastic rice.
