In a medium pot, bring the water to a boil. Add salt and rice and return to a boil. Lower the heat to low, cover with a lid and cook for 15 minutes without opening the lid. Then turn the heat off.
Remove the pot from the heat. Allow the rice to rest covered for 5 minutes in order to absorb all the liquid and steam.
Uncover the rice and fluff with a fork to separate the grains. Fold in the lime zest, lime juice, cilantro, and additional salt to taste, and serve.
