In a medium sized pot, heat the butter until it is brown. Add the lamp pieces and cook until it is tender.
Add the onion, carrots and leek greens and cook for 10 minutes.
Add the beef stalk and the rest of the ingredients, cover and cook in a heated oven 194 F for about 5 hours.
Take the lamb pieces out of the stalk and leave outside to cool, then shred the meat pieces and put them in some of the warm stalk to keep them warm.
Strain the stalk and leave about 3 cups to cook the rice in.
