The tongue is washed and boiled with salt, carrot, celery, bay leaf and pepper. Then it is peeled and cut into pieces and placed in the broth.
Separately, fry the onions and mushrooms. Add the flour, and put vegetables drained from the broth and cut. The roux is diluted with broth. Pour in the sauce, which you boil together with the tongue.
