There are so many ways to marinate and enjoy lamb. Give this one a try. You can modify the amount of lamb by serving two chops as opposed to the four shown here.
Add the first four ingredients to a food processor or a blender. While the machine is running, add a very think stream of olive oil and emulsify the mixture.
In a 1 gallon Ziplock freezer bag or small container add the prepped lamb rack and the marinade. Let marinate for 24 hrs, turning the bag or rack often to evenly coat.
