Add frozen mango, frozen pineapple, maple syrup, lime juice and rum to a blender. Blend on high until everything is combined. Add in a couple ice cubes and blend to your desired slushie texture.
If the mixture is too thick, add a bit of water & blend until desired consistency is reached. Garnish with lime or mint & enjoy!
Notes
Stores well in the fridge for a couple of hours. When ready to serve, blend again with a couple more ice cubes to reach desired slushie consistency.
