Sorry I couldn't give it five stars, with the following recommendation I'm certain it WOULD be five star!!! My simple, yet nessecary recommendation would be to boil a pot of water with a little salt, (maybe a teaspoon or so) and when you have your potatoes sliced Put them in the boiling water for 10 minutes or so, and allow them to cool, this will give them the softer consistancy that I think you would be looking for (for some reason I can never get potatoes to get that "tender" consistancy without boiling in these type of dishes)!!!! Follow my recommendation and you'll have five star AuGratin potatoes that you'll be proud to serve!!!
These turned out great when I tried them. I happened to have some light cream so I substituted that for the milk and I think it made it extra creamy.
