Frozen Fruit Smoothies

I went to a baking class last weekend, and there will be a post on that, but I'm behind on a lot of chores since a pothole ate the highway outside my house this week and I have a present to finish knitting and so: tonight we're talking smoothies.

I go through bouts of smoothie making fairly regularly, and this is one of my favorite standby smoothie recipes:

1 cup yogurt
1 cup milk and/or 1 cup orange juice
2 cups fruit of your choice
handful of ice

You do not need the ice if the fruit is frozen.  However, be careful with different types of frozen fruit as some of the tougher ones, such as mango, can do a number on your blender.  In fact, I must admit, I usually have a terrible time with mangoes -- a little overripe and they make your smoothie stringy, a little under done and they add nothing to a drink except bulk.   However, I love the flavor of mangoes and if anyone has any tips for how to blend them properly into a smoothie give me a shout out. Fruits I have particular luck with are: fresh or frozen strawberries, blueberries, blackberries, and peaches.  Bananas are good as well, although, like mangoes, if they're even a little too under ripe you cannot taste them.
