• There aren't any strict rules on which fruits to pair. Bananas are especially good in a smoothie because they add texture but their flavor won't overpower the other fruits.
• Use frozen fruit instead of ice. Ice will dilute the smoothie and can create a crunchy consistency. Either buy frozen fruit or seal fresh fruit pieces in plastic bags and put them in the freezer the night before.
• Mix your fruit with juice, milk, yogurt, or sorbet, depending on the texture and sweetness you crave.
