Remove the lamb chops from the fridge about 1hr prior to cooking.
Very lightly colour the chopped garlic in a little olive oil over medium heat, set aside and allow to cool slightly.

Add salt and pepper to taste.
Place griddle or fry pan on high heat and add 1 tbsp of olive oil.
Season lamb chops with a little salt and pepper and grill for 2 minutes on each side.
Remove them from the pan and allow to sit covered.
Return pan to high heat.
Once pan is hot deglaze with a touch of red wine or stock and reduce.
