For the boiled beef, rinse and drain the meat. Bring water to a boil in a large pot. In the meantime, fry the unpeeled onion briefly in a pan without oil. Add the meat to the boiling water (total cooking time approx. 2.5 hours). Add peppercorns (best in a spice ball or tea bag), salt and Burgl’s herb soup.
Reduce heat and simmer. If foam forms, skim it off in between. After 1.5-2 hours, add the cleaned root vegetables cut into medium-sized pieces. Continue to simmer until cooked through 2.5 hours. Remove the meat from the pot. Cover with aluminum foil and let the boiled beef rest for a while.
