This is from Meg!
Slice 1/2 cup (4-5oz) of pineapple into small chunks, divide evenly in Popsicle (or ice cube) tray and smush with a fork to get the juice out, fill rest of tray with coconut water (should measure out to approx 1/2 cup), freeze and enjoy!
If you don’t have a Popsicle tray ice cube trays can be used.
