Wax Paper vs. Parchment Paper

Wax paper vs. Parchment paper.  Is there a difference?  YES!  I thought they were the same thing!  How come no one told me?  Maybe I should have asked...

Last night I made a batch of pumpkin macarons and used parchment paper for the first time.  It was in the holiday aisle at Target. 

When I took the cookies off the paper, I had ah-ha moment!  WTH?  Why have I not used this earlier?  Doh!  They work as well as a silpat!

Rule:  Don't use wax paper for macarons!  Use parchment!  Works as well as a silpat! 

Lesson learned.
