You'll need a blender to make this summertime drink. If you use a high-speed blender like a Vitamix or a Blendtec, you may not need to strain it. Leaving it without straining also leaves some of the healthy fiber in the drink and you'll have a refreshing drink with a pulpy froth on top. However, I've tried it both ways in my Vitamix and I preferred the strained version. It's less like a smoothie and more like a mocktail!
