Definitely helps to have Grandma's old school blender--
it works better than anything they make today!
Blueberry Banana Blast Smoothie
2.5 Ripe Bananas
1 cup Blueberries
2.5 cups Milk (or unflavored soy milk)
In your blender, pour about 1 cup of the milk in and add blueberries. Blend well on a high setting, until there are no blueberry clumps. (You won't be able to completely mix in the blueberry skin, but that's okay.
Add another cup of the milk and the bananas. Start on a low setting, increasing to high as the smoothie starts to come together. Check periodically on the consistency: if it's too thick, add the remainder of the milk.
Yields about 5 cups.
