What can I say other then the suspicions I had with the Wisconsin Cheddar Lay’s have been confirmed when I finally re-experienced Au Gratin Wavy Lay’s. Other then the obviousness of these being wavy cut chips versus the flat cut on the Wisconsin Cheddar. The flavors are pretty much the same other then the Au Gratin having less cheddar overtones then the Wisconsin Cheddar version. Surprisingly I actually prefer the Au Gratin to the Wisconsin Cheddar, since I really don’t care for the pronounced sharp cheddar cheese flavor on the Wisconsin Cheddar. But hey, to each their own.
