Sautee the rice in butter until almost translucent (as if you are making a risotto).
Add water, bring to a boil.
As soon as the water begins to boil, turn the heat down low.
Simmer, covered for 15-20 minutes, or until all water is absorbed.
Turn off heat. DON’T PEEK. LEAVE IT COVERED for 30 minutes (this is the “steaming” part…. Chipotle steams rice every hour). This is what makes the rice fluffy. You won’t be happy with yourself if you don’t do this. Be patient. Good things come to those who wait.
Remove lid, let some of the steam out. It may be helpful to transfer rice into a mixing bowl for the next step.
Mix salt and juice of key lime together until salt is dissolved.
Pour it over rice, fluff with a fork.
Sprinkle in cilantro, and toss well to evenly coat with cilantro and lime mixture.
