Pineapple: For best results, use canned crushed pineapple in pineapple juice. I do not recommend fresh pineapple.
Sugar: Both granulated sugar and cane sugar work for this recipe. Cane sugar is minimally processed so I personally like to use that more.
Leftovers: Leftover rice will keep refrigerated in an airtight container for up to 4 days. It reheats very well too. To reheat the rice, add the rice to a non-stick skillet with little fat, such as butter or swirl of oil and heat, stirring occasionally, over medium heat.
