Having lived in America for the past three years I've gotten a little better with Mexican food in general - but I'm still trying to tune my burrito filter. They all still taste pretty flippin' good to me.
My favorite burrito served at the Mexican place down the street from my house is the beef tongue (or lengua). I decided to treat myself earlier today.
Tongue is not only a great economy food (there's a lot of food in one tongue) but as I've demonstrated in other posts (salad, sandwich and main course) it's very versatile.
I may not know much about Mexican food, but I know a little about tongue, and I sincerely advise everyone to go try a tongue burrito for lunch soon. Your tongue will welcome the company.
