Instead of using water when making a smoothie, use a bottle of orange juice instead. You will be glad you did. Why settle for a weak flavor when you can crank the flavor knob right up to eleven!
If you buy a case of these 10-ounce bottles at your typical warehouse store (or Amazon, if you click the image), you'll be ready for your next smoothie adventure. I found that if you are making a smoothie where you've filled a Four-Side jar up to the top with a mix of fresh and frozen fruits, one 10-ounce bottle does the job nicely. No more wimpy weak watered-down flavor.
