Rice pudding takes on tropical flavors when coconut milk is added to the custard mixture and chopped mango is used as the topping. Arborio rice, which is the type used in making Italian risotto, is also the best option for this pudding, too, since it has a firmer texture that makes for a more toothsome consistency. Be sure to rinse it well before using to remove the excess starch, and to stir the rice frequently while cooking.
