Combine all the marinade ingredients and mix well.
Pour over the lamb chops and allow to marinate for at least 10 minutes (a few hours is preferable).
Pre-heat a griddle pan or grill and grill the lamb chops until caramelized on the outside and blushing pink in the center. Stand the lamb chops up on their fat side to make sure the fat renders and becomes crisp and golden.
Allow to rest for 5 minutes then serve with tzatziki.
