Combine the rice, coconut milk, water, and pinch of salt in a 2-quart saucepan. Bring to a simmer. Stir a few times at beginning to separate the rice, then cook undisturbed, partially covered at a gentle simmer until liquid is absorbed, about 12-15 minutes. At 12 minutes check the rice for doneness.
Remove the pan from the heat and let the rice rest, covered, for 5 minutes. Then, fluff the rice with a fork and stir in the lime zest, lime juice, and cilantro. Season with more as needed. Taste the rice and add more fresh lime juice if needed.
