Soak kebab sticks in water for 15 minutes. Preheat the oven to 200°C. Season the lamb with salt and pepper and drizzle with oil. Skewer onto kebab sticks.
Heat a pan and place the skewers into the pan sear each side till browned. Once browned add in the butter, rosemary and garlic. Toss and place into the preheated oven for 5-10 minutes, depending on preferred doneness. Remove from the oven and allow to rest while you prepare the sauce.
For the sauce, place all the ingredients except the mint jelly into a saucepan and heat until the sauce starts reducing and thickening slightly. Finish off the sauce by stirring through the mint jelly and fresh parsley.
Serve the skewers on a bed of micro herbs and either pour the sauce over the skewers or serve alongside the skewers for dipping.
