We learned some very important lessons tonight!
1. Always ask if the proper equipment is available for your project!
2. Do not use glassware for making caramel popcorn.
3. If a chunk of your favorite Pampered Chef spatula breaks off during the stirring of the caramel into the popcorn, it well very well delay, and therefore destroy, said batch....
I did find the missing piece after much searching, but sadly by then the caramel had set, and the batch was weird, delicious, but weird.
