In a medium saucepan, combine Jasmine rice, water, unsalted butter, and crushed pineapple with juice. Add kosher salt and granulated sugar, stirring until well mixed.

Place the saucepan over medium-high heat and bring the mixture to a vigorous boil.

Reduce the heat to low and cover the saucepan with a lid. Let the rice simmer gently for 15-20 minutes.

Once the rice is tender, remove from heat and let sit covered for about 5 minutes. Add lime juice and fluff the rice with a fork, garnishing with chopped green onions.
