In a bowl place the sugar, ginger, cinnamon, tarragon, pepper, garlic powder and salt and mix well together.
Now take this seasoning mixture and rub well into the lamb chops on both sides then place on a place and cover.
Then place in the refrigerator for an hour.
To cook the lamb chops you must remove them from the refrigerator whilst the barbecue is heating up to bring them back up to room temperature and they need to be cooked on a high heat.
As usual brush the grill of the barbecue with some oil first before laying the chops on it.
Then cook the chops on each side for around 5 minutes or until they are cooked the way you like them.
Once they are cooked allow them to rest for a few minutes before serving with a salad and some new potatoes.
