After this time, add the meat stock, previously heated in a saucepan. Leave the meat to cook for approximately 90 minutes.
When the meat is tender, remove the vegetables and add a little corn starch to the juice to thicken it and get the desired texture.
Meanwhile, wash the mushrooms well and cut them into medium-sized cubes. 15 minutes before the end of the cooking time, add them to the casserole with the stew and let them finish cooking.
