If it is cooked right, Lengua is wonderful in a breakfast taco with some potatoes, and good salsa. Yummm, very lean, and very tasty. Home made soft corn tortillas are also wonderful.
I'm planning on going into my new favorite Mexican joint to try their beef tongue this weekend, unless my friends want to do their breakfast instead. I have never had beef tongue but I have heard it tastes like pot roast. Last time I was in I tried their house made soft corn tortillas despite them being forbidden on my diet. I found out what I been missing all this time. Every soft corn tortilla I had had up to that point has been garbage. These were magnificent.
