Use the leftover pineapple juice to make popsicles. Fill the popsicle mould and pop it in the freezer. It’s a refreshing and cooling dessert for kids on scorching summer days. Another best option is freezing pineapple ginger juice in an ice cube tray. Use the flavoured ice cubes in cocktails, mocktails, and smoothies or add it to a jug of water and turn it into flavoured water.
