First prepare the beef: Trim the meat of any excess fat.
Rub the sugar well into the beef, then place in a bowl, cover with plastic wrap, and refrigerate for 12 hours.
The following day, using a mortar and pestle, grind together the spices, saltpeter, and salt. Rub the spice and salt mix over the meat, re-cover, and refrigerate for 6 to 7 days, turning daily.
Transfer the beef to a large, heavy-bottomed saucepan, add the turnip, and cover with cold water. Bring to a boil and then let simmer for 2 hours. Lift out into a serving dish and let cool.
Serve cold.
