World-famous chef Jean-Georges Vongerichten is so fond of his wife Marja's ultrarich mac and cheese that it appears on the menu at the Mercer Kitchen, one of his New York restaurants. Marja makes the dish with four cheeses, from creamy Monterey Jack to extra-sharp cheddar. The most unusual touch: the cubes of cream cheese that melt on top. Can be made ahead, see last note under the directions. From "Food and Wine" magazine.
