In a large pot, add the pork bones, a piece of bacon, onions (with cloves in them), carrots, leek and a generous amount of thyme. Add water and simmer for 2 hours to create a flavorful stock.
Sieve it, and boil the beans in this.
Boil the pork rind in water for 2 hours. In the same water, cook the peeled garlic bulbs. Blend the cooked garlic into a creamy consistency. Season with salt to taste. Keep the pork rind.
Fry the pork ribs and sausages in some duck fat from the confit until browned.
In an ovenproof dish (preferably terracotta, wider at the top than at the bottom), layer as follows: beans, pork ribs, beans, sausages, beans, duck legs from the confit, finishing with a final layer of beans. Pour the garlic cream mixture over the top and drizzle with a little duck fat.
Bake: Preheat the oven to 160°C. Bake the dish for two hours.
