Initially, I made this dish as a way of recreating a family Christmas Dinner. The challenge, create a dish the way that Karen's mom, Lois - an excellent cook, would serve.
Now, this dish is one of the must-have standards for any major holiday meal. It would not be Thanksgiving without turkey and whipped potatoes. Ditto for Christmas.
The ingredients are from the original recipe, but I have modified it as I am not a fan of recipes that say "four large.... I use this recipe for up to 5 pounds potatoes, using 1 cup sour cream, 2 cups cottage cheese, 3/4 cup butter. That will nicely fill a large baking dish.
