Lengua Tacos : Beef Tongue Tacos

1 beef tongue
5-7 peppercorns
4 bay leaves
1 onion cut in halves
5 whole garlic
3 tbs salt
6 tomatillos
3 jalapeños
1 serrano
1 garlic
1/4 onion
I used a instant pot but you can also use a crock pot.
Place tongue in instant pot and put enough water to cover tongue. Add onions, peppercorns, garlic, salt and bay leaves. Cover and cook for 1hr 45 mins. If using a crock pot, cook for about 8-10hrs. Once done, remove too layer from tongue. Cut into small pieces, I add some of the broth/juice to the meat to keep it juicy. Too with salsa, lime, onions and cilantro!
Boil all ingredients besides cilantro. Once done, blend in blender and add cilantro. Season with salt.
Enjoy !!
