Agua de piña is a refreshing and delicious rice drink made with pineapple rinds and milk. This dairy-free version of traditional horchata is a perfect summer beverage, with its creamy texture and sweet, tropical flavor.
Peel the pineapple with a knife and save as much of the skin as possible. Set skins aside.
Boil 5 cups of water in a medium pot or saucepan. Add pineapple skins, rice, and cinnamon. Cook for 25-30 minutes or until rice is cooked and pineapple and cinnamon are fragrant.
Remove from heat and cool for 10 minutes. Remove pineapple skins and cinnamon sticks.
Transfer rice and water to a blender. Add milk, sugar, vanilla, and pineapple meat to your liking to the rice and water.
Blend for 30-45 seconds or until smooth.
Pour into a glass and garnish with shredded coconut or pineapple chunks.
You may chill the arroz con piña in the fridge or add ice cubes to cool instantly.
