My friend, Ross, introduced me to the wonders of the Silpat. Sure, I had seen them used before, but I didn't actually use one until I helped Ross make over 200 6" cookies for an event.
So what is a Silpat? "The most popular non-stick baking item ever invented," according to their website (Silpat.com). It turns your cookie sheet or counter in a non-stick surface. It saves a lot of time cleaning up because the pan doesn't have any sticky mess on it. I simply wash the pan and Silpat with hot soapy water.
I used to us parchment paper all the time, but now I pull out my Silpat instead because it not only saves clean up time, it saves waste and money. I still use parchment paper from time to time, just not as much.
