Identify that Chewed Item!

My blog is now going to become an interactive game! I am going to post random pictures of things that Sailor has chewed up and let you all in on the guessing game fun that Corey and I play several times a week...First up, can you identify this substance?

At first glance, we thought it was ground beef. I was utterly baffled. Corey was able to correctly identify what it used to be in record time.

Yes, that's right! A cork coaster!
