Ribs With Potatoes

Preparation:

Preparation: Cut the ribs separating them from each other, ie forming as many pieces as there are bones. Brown them in butter and oil and add - then - the chopped celery, onion and carrot, leaving to infuse. Season with salt and pepper and add the tomato sauce diluted in a couple of ladles of broth; cover with the lid and cook for about an hour and a half. Add the potatoes, peeled and cut into large pieces and finish cooking by adding more broth if necessary.
