@Lustig Andrei,
I've read that real rendered lard is better, fats wise, than butter, and the numbers back that up, should you care. I like them both, of course. The superbaddie is the hydrogenated stuff in packages in my grocery store (they're blue, as it happens, the packages). I made my polenta with home rendered lard this week (I was out of butter, usually more tablespoons anyway).
Andy, I have memories of going to a family type lodge like restaurant with my husband, his bro, and in laws, and our table being honored with a large (7 or 8" wide, 5" deep) bowl filled past the brim with margerine). I also remember packets to color margerine when I was maybe four.
