Although lard is bad for you, the grim truth is that tortillas taste very much better when they have been fried in lard. Crumble anejo on top of those layers, then sprinkle finely-chopped coriander on top of that. Bake for 5 minutes, or until the cheese has melted but not browned. Remove from the oven, and use a pizza cutter to slice into individual portions. If you're desperate, you can use Armenian mozzarella, which has the right texture but the wrong flavor.
Anejo cheese is somewhat like Parmesan, dry and crumbly.
You can substitute Mexican cotija cheese, but that is probably pointless, because a store that carries cotija will probably also carry anejo. Fresh-ground parmesan will do in a pinch, though it is not the right flavor. In one of my many attempts to get this recipe right, I tried a mixture of Greek feta and cow's-milk romano cheese. It tasted very interesting, though not at all authentic. Another creation of The Master's Tech .
