How much water or broth for 4 cups of rice?

if you want to cook rice as how Filipinos eat rice, then the ratio is 1:1... turn down fire or heat to a minimum when you dont see water on top of cooked rice.... remaining water in below the surface will be enough to fully cook the grains.

2-4 cups to 1 cup of rice grains makes "lugaw"... that's a soup like consistency.
