Wash the meat and dab dry. Season with salt, pepper and rosemary. Place on the fat pan of the preheated oven (electric oven: 200 °C/ gas: level 3) and cook for approx. 1 3/4 hours.
During the last 1/4 hour, pour 1/4 l of water over it. For the vegetables, peel shallots and red onions, possibly halve them. Clean, wash and cut the spring onions into bite-sized pieces.
Drain the apricots and collect the juice. Melt the sugar in a large pot until golden brown. Deglaze with vinegar and 1/4 litre water, bring to the boil. Add bay leaf, peppercorns and prepared onions.
Season with salt. Cook for about 12 minutes. Add the apricots 3 minutes before the end of cooking time. Then loosen the roasting mixture and pour it through a sieve to the vegetables. Season to taste with some apricot juice if necessary.
Arrange everything on one plate. Serve with fresh baguette.
