Mix 1 1/2 cups long grain rice, 1 14 ounce can coconut milk, 3 Tablespoons granulated sugar, and 3/4 teaspoon salt together in a rice cooker. Start rice cooker. When finished, fluff with a fork and serve.
Notes
If you don't have a rice cooker, stir ingredients together in a medium saucepan. Bring to a boil over medium-high heat. Cover and reduce heat to medium-low. Simmer until liquid is absorbed, around 15-20 minutes.
