Big is better This smoothie uses quite a few bulky veg, so you need a big blender to make it all in one go. If you have a smaller blender you can make it in two batches, using half the ingredients each time, or blend the cucumber and apple with half the maple water and pour it into a large jug. Then blend the remaining ingredients together and stir them into the cucumber and apple mix.
