In a medium size pot, bring water to a boil, add a dash of salt. Rinse the beef, pat dry. Place beef in boiling water (pores will close immediately, fully preserving the flavor of the meat). Add the root and onion vegetables (Suppengrün) as well as the peppercorns and juniper berries to the pot. Cook meat for about 2.5-3 hours. Halve and brown the onion and add it to the pot for the last half hour (this adds flavor and color to the stock).
