You can make nice milk shakes with ice shaved into it, but a really nice treat is a yogurt-milk shake:

Raspberry Yogurt-Milk Shake

Take 5 oz of yogurt, drain it over night or at least for a few hours. Add 5 oz of milk plus 1 – 3 teaspoons of Torani Raspberry sirup (depending on how artificially sweet you like it, or not).

Put this all into a glass and mix it with a whipping motion with a spoon (or use a blender if you want to clean more dishes) until well blended and airy.

This gives a really nice shake with good consistency with the very mild tartness of the yogurt underlying. Really good if you are tired of milk-ice shakes.
