While Argentinean bakeries use a special bread cut very thinly from an extra large pullman loaf, you can still make these sandwiches at home using a standard loaf of white bread. To finish them properly, be sure to trim off the crust after you assemble the sandwich. What to do with the extra crust? You can, of course, eat that too.
