Lengua a la Vinagreta
A classic Argentine dish.
Boil the tongue for 2 hours per kilo, in this case, 3 hours. Add a rough chopped onion, carrot, celery, leek, and bay leaf to the boiling water with the tongue.
Once the tongue is tender, peel off the outer layer, then slice it thinly.
Dice up a red pepper, one bunch of parsley, 4 hard boiled eggs, and two aji amarillos. Add the zest and juice of one lemon. Put all of this in a bowl with a 2:1 ratio of EVOO to vinegar.
Add the tongue slices, and mix everything well, so the meat is fully marinated. Put this in a dish, and let chill for a few hours at least, or several days for best results.
Delicious!!!
