OK, forgot to check back here. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Blush.gif" alt="" /> I didn't substitute out any cheese, but used all parmesan (no canned stuff!!). It was very good, but too salty, as I didn't ramp down enough on the added salt. Very rich.. Wouldn't be my regular scalloped type potatoes. Except for special occasions, I might do half heavy cream and half milk or something..
