Place 1 cup of dry jasmine rice and 1 ¼ cups of water in a saucepan over high heat. Add a pinch of kosher salt and a tablespoon of butter, if desired. Bring to a boil.
Cover the pan with a lid, reduce the heat to low, and allow to cook for 10 minutes without lifting the lid.
Remove the pan from the heat and let the rice rest for 10 minutes. Fluff with a fork before serving.
