Move constantly with a wooden spoon
Meanwhile, boil the 3 cups of water

Add a cup of boiling water and mix it
Let it simmer for about 40 minutes, keep a close eye and add more water as needed, you'll need to move it with a wooden spatula to avoid having a burnt rice

Optionally, slice the banana and add it to the rice, or add some cilantro if you want
