If only I could justify using a POUND of butter...

This recipe just blew me away. Whipped potatoes with garlic and cheese from Saveur, courtesy of my RSS reader. I am sure they are great, mainly because they call for cooking the potatoes in a POUND of butter, but who in the world can use that much butter for 6-8 servings and still sleep well at night? I did the math. Assuming you shared with 7 other people, that's still 400 calories a serving in butter alone. That doesn't count the cheese and potatoes in the recipe. I love mashed potatoes more than anything, but I don't think even I could come to terms with making these. Still I have to wonder how rich and creamy these potatoes would be...
