Traditional recipe
Cut the pork shoulder or loin into cubes and marinate with thyme, eau de vie, pepper and 2 tablespoons oil.
Cover with white wine and leave overnight. The next day, drain the pork cubes and roll them in flour. Brown the meat, and then the thinly-sliced onions. Cover with the marinade, the stock and the red wine and leave to simmer in a covered saucepan for 2 hours. Blend the blood with the crème fraîche and simmer with the sauce for a further 15 min.
