It’s tough, if not impossible, to get perfect smoothies without a blender but that doesn’t mean you can’t enjoy a smoothie when there’s no blender available. To make a smoothie without a blender: cut the recipe in half and add all ingredients, plus two ice cubes, to any cup or jar with a lid, then shake vigorously. Blender containers made for protein powder work especially well as blender alternatives if you want smoothies on the go.
