– Place the beef tongue in your instant pot along with the onion, garlic, and herbs. Cover with water and cook for 30 minutes. If using a regular pot, cook over medium-high heat until it comes to a boil. Reduce the heat and gently simmer. Cook until it is tender, about 2 hours. Make sure that you cook it until it is tender, but still firm enough to cut into slices.
– Once the beef tongue is cooked, wait until it has cooled and then remove the outer skin. Cut into ⅓-inch slices and set aside.
– While the beef tongue is cooking, heat 2 tablespoons of oil in a large skillet over medium heat. Fry the bread slices until they are a light golden brown, turning once. Set aside.
– In the same skillet, fry the almonds, onion, and garlic clove for about 8 minutes.
– Add the tomatoes and keep cooking until the tomatoes have released their juices.
– Place this tomato-almond mixture into your blender and add the clove, peppercorns, cinnamon, and sherry. Process until you have a smooth sauce.
.– Using the same skillet as before, heat the rest of the oil at medium heat and then pour the tomato–almond sauce in. Add 1 cup of the beef tongue’s broth and gently simmer for about 15 minutes. Season with salt.
– Add the beef tongue slices and keep cooking for 8 more minutes, until the sauce has reduced.
