When I asked my friend Roberto Santibañez, chef/owner of Fonda in Brooklyn, New York, and on Avenue B in Manhattan, about albóndigas (al-BONE-dee-gahs) he told me his grandmother brought her meatball ingredients to a butcher in Mexico City and asked him to run them through the meat grinder along with the beef she purchased there. I doubt your local butcher would take your request seriously if you showed up with the ham, onion and hard-boiled eggs for
