This is a crockpot version using the rub that my mother-in-law uses. It turned out really well and was very moist. Lamb in the oven tends to dry out.
Lamb (I used a small shank (1 1/2 lbs), but for a larger group you can use a whole leg)
2 tsp dill
1 tsp rosemary
1/4 tsp pepper
1/2 cup wine
Rub lamb with spices. Place lamb in crockpot and pour in wine (without washing spice rub off lamb). Cook on low for 4 hours for a small lamb shank; a large leg will take about 8 hours on low.
