To prepare a sticky rice with coconut milk and mango recipe, you will first need to gather your ingredients. You will need: 1 cup (240 ml) rice, 2 tablespoons (25 g) coconut oil, 1 tablespoon (2.5 oz) mango, and 1 teaspoon (0.02 tsp) kosher salt. Heat the oil over medium-high heat. Add the rice and cook, stirring occasionally, until it begins to turn golden brown, about 5 minutes. Remove the pan from the heat and stir in the mango. Serve hot with sour cream, if desired.
