The best trick for thick and cold smoothies is to nix the ice altogether, and instead replace ice with frozen fruit. If I remember I try to prep some fruit ahead of time, like peeled and halved bananas, and cored strawberries. They thicken the smoothie very nicely and since they are mostly made of water anyways, they act as a superb ice, with way more flavor.
I also use plain yogurt, regular or greek, and the liquid part is usually whatever juice I have on hand. If I'm lucky and have it on hand, I love using Acai juice (so many antioxidants!). One more trick, if you are having trouble with an old blender, add the yogurt and only a portion of your frozen items (strawberries or banana), blend it, then add a bit more, blend again, and repeat. Sometimes old blenders aren't as effective, but this method really works, just take it in stages.
I'd love to know your favorite smoothie combinations, let me know what you got!
