Sauces, oh my, yes. Love 'em, both simple and complicated.
At home, definitely simple -- for example, a nice mouth-filling meat sauce for pasta. I CHEAT by starting with a can or three of Hunts -- I always forget the name, but it's the only one that for some reason doesn't include HFCS in the ingredients. Brown a pound or three of decent ground beef (I've tried other meats but they just don't quite satisfy in the same way), being sure to season with fresh ground S&P. Lightly sautee some chopped/crushed fresh garlic in a little olive oil. Fresh basil if I have any. Simmer it all together until you can't stand it any longer.
That's for "hearty" eating. Perhaps someone can post something a little more delicate.
