For this easy, impressive hors d'oeuvre, Jacques Pépin tops roasted fingerling potatoes with sour cream and slender diamonds of pressed caviar. Boiled, sliced red potatoes also work.
Black beans mingle with onions, peppers, garlic, cornmeal, and spices in this tasty taco filling. Try it in burritos or as a dip for tortilla chips. No black beans? Red, pink, or pinto beans are great subs.
