These can be pretty amazing if prepared right. Steak author Mark Schatzker says "You can braise tongue, and it's really good. There are nice recipes online. Or, the Japanese way is to half freeze it, then cut a 3 inch section, turn upright and slice the skin off. Then, slice medallions across the grain. Think thin medallions.

Sprinkle some salt on them after they cook, and enjoy."
