PURPLE COW 
( have you ever seen one?)

One tall glass

¾ Cup Milk

1 ½ Tablespoon frozen, concentrated grape juice

¼ 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!
