Cooking Rice

I can't understand why our cafeteria can't cook steamed rice properly. It's not like they're cooking it over a stove top... they have a huge rice cooker! For some reason, the rice is often semi-cooked so it's hard and crunchy, not fluffy like steamed rice is supposed to be.

I used to cook rice for my old church in Lomita. We would use 4 extra large rice cookers to cook rice for 100+ people and it always came out perfect.
