How To make Irish Spiced Beef

6 1/2 lb Beef
3 x Bay leaves
10 x Cloves
5 x Blades mace
Crushed clove garlic 1/4 c Brown sugar
1 lb Salt (about 2 cups)
1 1/2 tb Saltpeter
1 Bunch fresh herbs
3 Sliced carrots
3 Sliced onions
NOTE: prepare 7 days in advance of eating! -- Wipe meat over with a damp cloth. Mix seasoning ingredients together except for carrots, onions and fresh herbs. Rub seasoning well into meat; then lay mean on bed of seasoning. Leave in a cool place (preferably not refrigerated, though). Repeat rubbing each day. On the seventh day, put the meat into a saucepan and cover with cold water. Bring to boiling point and simmer gently for 5 hours, when it should be tender. Put cooked meat on a flat dish and cover with a board. Set weight on top of board until meat is cold, when it is ready to carve and eat.
