You can marinate the Lamb overnight, however I had marinated only for 4 Hours.
Sometimes the Lamb takes more time to be cooked, in case the Lamb is not cooked for you properly, then keep it in simmer/low flame for more duration.
It is not advisable to add any water however in case your Lamb is getting burned, sprinkle little bit of water.
Use a good non-stick skillet to make this recipe.
The Lamb Chops needs lots of patience, you can't make it quickly.
