Talked to a American born Mexican descent friend of mine, he says:Queso Asadero translated is Cooking or Grilling Cheese.Is white and normally comes in round or square blocks.Is not normally used for dipping cheese, maybe your restaurant/info is different.Cheers, John.
Asadero: Also called queso quesadilla because of its usefulness in that dish. Usually sold sliced, asadero melts well and can be used for nachos or burgers. You can substitute Teleme (referred to as a "poor man's brie from California) or Muenster cheese.
This is specifically a melting cheese, used to make the Mexican fondue called queso fundido, a dish which adapts well to the inclusion of a variety of ingredients and is usually eaten as a late-night supper. Fontina and Monterrey Jack are fine substitutes.
I have an Asadero Cheee Making Recipe , just need to post and no time tonight as Daughter #1's 17th birthday.
