01 - In a small bowl, combine olive oil, minced garlic, rosemary, sea salt, and black pepper. Rub the mixture evenly over the lamb chops and allow to marinate at room temperature for 15 minutes.
02 - Combine chopped mint leaves, granulated sugar, white wine vinegar, and water in a saucepan. Bring to a gentle boil, stirring occasionally until the sugar fully dissolves.
03 - Remove the saucepan from heat and let the mixture cool slightly. Sprinkle powdered gelatin over the liquid and stir thoroughly until fully dissolved. Transfer the jelly to a small jar or bowl and refrigerate for at least one hour until set.
04 - Preheat a grill or grill pan to medium-high heat, ensuring it is properly heated before cooking.
05 - Place lamb chops on the grill and cook for 4 to 5 minutes on each side to achieve medium-rare doneness or adjust timing to preference. Remove from heat and allow to rest undisturbed for 5 minutes to retain juiciness.
06 - Plate the grilled lamb chops and accompany each serving with a spoonful of chilled mint jelly on the side.
