Cut the three types of meat into bite-sized cubes and marinate in white wine overnight.
The next day, cut the potatoes and onions into thin slices. First line the soaked Römertopf with a layer of potatoes. Then continue in layers with the meat cubes, the spices / herbs and onions.
Salt and pepper each layer. Repeat the procedure one more time and finish with a layer of potatoes.
Pour the wine stock over and cook in the oven, covered to 220 ° C, for 1 1/2 hours on the lower rack. Then pour in a glass of white wine and cook for another hour on the middle rack at 160 ° C.
If you do not want to heat up the oven beforehand, as the manufacturer says that Roman pots are put into the cold oven, the time is increased by approx. 15 minutes.
