-approximately Sea salt Freshly ground pepper Place the beef between two sheets of plastic wrap and pound, pushing it outward as you go, to a rough oval shape. Fold into a package and pound out again to the required size. Peel off the top plastic wrap and replace with wax paper. Turn meat over and replace second sheet of plastic with wax paper; set aside until ready to use. Heat a griddle. When very hot, grease lightly. Remove top paper. Sprinkle the exposed side of the meat with lime juice and salt and pepper and lay it face down, with the aid of the paper, on the griddle. Strip off the bottom paper. Cook for about 2 seconds, flip the meat over with two spatulas so it will not break in the middle, and cook for 2 seconds more. Serve immediately, flat if possible, on a large plate with refried beans, and fresh salsa of your choice. The Art of Mexican Cooking From the collection of Jim Vorheis
