Just in case anyone is wondering how to remove the deer tongue, I found that making a cut from the chin to the throat and then wrestling it out from the bottom to be the easiest method. After you remove the tongues I would suggest letting them lit in a cold water bath for a day or so changing the water three or four times.
After you tongues have soaked all you have to do is simmer them for a couple hours let them cool and peel the skin off your tongues. Once they are cooked it is just a matter of soaking them in a pickling solution. After they are soaked in the pickling solution they are ready to eat. In Picard's book he suggest browning them with a little but and serving them with some crusty bread and some spicy brown mustard. I can tell you that this a perfectly suitable way to eat them. I enjoyed it tremendously, however, I have five of these tongues and wanted to try something different.
A while back my wife and I were at Piccolo a restaurant in minneapolis that is home of the best thing I have ever eaten. Scrambled brown eggs with pickled pigs feet, truffle butter and parmigiano, I know it sounds odd but so far in my life I have not eaten anything that could top it. So I thought why not try something similar with the pickled deer tongues. Now, I am no Doug Flicker but my scrambled eggs with pickled deer tongue, asiago and truffle oil wasn't the worse the thing I have ever had. I think I over cooked the deer tongue when I chopped it up and browned it in butter. The flavor was all there but I remember the pigs feet being as soft as the eggs and them blending together better. My tongue was a little crisp and not as subtle. Not bad, just not as good as the original.
The good news is I still have some more tongues to experiment with and I am looking forward to finding something else I can do with them. I am not sure what to do next with them but what ever it is I am sure it will end up on here.
