Love the ice cube trays they are so versatile and easy to use. I make ice cube for my water in summer using slices of lemon and lime and sprigs of mint and squeeze of lemon juice. I also make my grandson smoothy ice blocks and icy poles with the paddles rated on top of the ice cubes, make sure your smoothy mix is thick if using the paddles. Banana and mixed berries and some coconut cream is very yummy mix.
