Grandpa Karsky was the grandfather of my daugter's now ex-fiance and from what I hear he was a great cook and a wonderful guy. He passed away before we met the family. It's too bad his grandson didn't follow in his footsteps in being a wonderful guy! :-) This is another Grandpa Karsky recipe and it is creamy and delicious. Not your ordinary potato recipe. The recipe says to refrigerate overnight, which of course you can do, but you can also bake it right away for around 20 - 30 minutes or until it is heated through. Because it can sit overnight it makes it a great recipe for any party because it's already made and you just pop it in the oven! Grandpa Karsky was aparently famous for shortening recipe instructions so I have embelshed this one a bit. Also, sometimes the potatoes are too dry for my tatstes so I've added some milk or some extra sour cream to make them creamier. I have also sprinkled cheese and/or bacon during the last 10 minutes of baking.
