Tongue stewed in wine

Wash the tongue and put it in a large casserole with water and salt and leave to cook for 3 hours, until the tongue is cooked, set aside and peel the tongue and cut it into slices of about 2 cm, we can also do this in a fast cooker and leave the tongue to cook for 1 hour. Another easier option is to buy the tongue already cooked. To make the sauce, put a little olive oil in a casserole dish, chop the vegetables and fry until lightly browned. Add the red wine and turn up the heat so that the alcohol evaporates. Spread out the slices of tongue, cover with the stock or water, add the spices and leave to simmer for 1 hour.
