In my culinary arts classes I love using episodes of Alton Brown's Good Eats tv show to supplement my content. I find Good Eats provides all the information from the text book in a more entertaining, easy to understand format.
This is a group of 4 episodes going over Dairy with a total of 20 questions. The episodes are:
The Case for Food
For Whom the Cheese Melts
Yogurt: Good Milk Gone Bad
