Prepare the bread dough according to the instructions on the packet. Cover the dough with a towel and let it rest for about 30 minutes in a warm place.
Wash the herbs, dab dry. Pluck leaves of parsley and thyme from the stalks and chop finely. Cut chives into small rolls. Mix herbs and spread on a board. Dab smoked pork loin dry, rub with mustard and roll in the herbs.
Roll out bread dough rectangularly (approx. 25 x 35 cm) on a floured work surface. Place the cured pork on top, cover with bread dough and place on a baking tray lined with baking paper with the seam facing down.
Cover with a cloth and let it rest for another 15 minutes in a warm place.
Coarsely crush mustard seeds in a mortar, mix with cumin. Brush bread dough with water. Spread the spice mixture over it. In a preheated oven (electric cooker: 175 °C/ circulating air: 150 °C/ gas: see
manufacturer) cook for about 1 1/2 hours.
Peel and quarter the shallots. Peel garlic, dice finely. Caramelise sugar in a pot, deglaze with red wine. Add shallots and simmer at medium heat for about 30 minutes. Season to taste with vinegar, salt and pepper.
Remove the smoked pork from the oven, cut into slices and serve with red wine shallots. Sprinkle with chopped parsley if desired.
