Wash the meat, pat dry and rub with salt and pepper. Roast on the oiled fat pan of the oven in the preheated oven (electric cooker: 200 °C/recirculating air: 175 °C/gas: level 3) for 1 1/2-1 3/4 hours
In the meantime, peel, wash and roughly dice the potatoes. Clean and wash the vegetables. Cut carrots into pieces, zucchini into slices. Wash herbs and chop separately
Dissolve stock in 1/8 l hot water. Distribute potatoes, vegetables, bay leaf and thyme around the roast about 40 minutes before the end of the cooking time. Pour stock over the vegetables. Season with salt and pepper
About 5 minutes before the end of cooking time, spread the roast with jam and encrust it. Arrange everything, sprinkle with parsley
Let the roast rest covered for about 10 minutes before slicing - this way less meat juice escapes
