Never had it fried. Had it the other ways mentioned here tho.
Here's a recipe which includes fried tongue:
Ingredients
•1 cow tongue
•1 large or 2 small leeks
•1/2 an onion
•3 carrots
•1/2 red bell pepper
•1 tomato
•flour
•2-3 eggs
•salt
•white wine (optional)
Instructions
1.Coarsely chop up all the veggies and place them in a pot with just enough water to cover them.
2.Place tongue in pot (the cow’s, not yours). It’s not that important that it be completely covered by the water, because you can turn it a few times while its boiling.
3.Add a few pinches of salt (2-3 teaspoons?)
4.You can optionally add about a glass of white wine, as well
5.Boil for 60-90 minutes, depending on the thickness of the tongue.
6.Allow to cool
7.While it’s still warm (it’s easier when warm), remove the skin from the tongue.
8.Cut into thin cross-section slices. The thinner the better.
9.Purée the vegetables in the pot. We use a handheld mixer (see photo below).
10.Bread and fry each slice
1.Heat oil in frying pan (we use sunflower oil)
2.Pour some flour on a plate
3.Beat 2 or 3 eggs in a bowl
4.Cover each slice of tongue in flour
5.Dip each slice in egg
6.Place each slice in hot oil until golden brown
11.Place each breaded and fried slice in the pot with the sauce
12.Simmer on low heat for a few minutes to let the flavors mingle
13.Serve with a healthy serving of silly tongue jokes.
