Have you ever seen one?

One tall glass
3/4 Cup Milk
1 1/2 Tablespoon frozen, concentrated grape juice
1/4 Cup vanilla yogurt

Measure the milk, frozen grape juice and yogurt into a container with a tight lid.

Hold onto the container and lid firmly and shake like crazy until everything is mixed and foamy.

Pour it into the tall glass.

Get a purple milk mustache! Enjoy!
