Prepare the Kofta Mixture: In a large bowl, combine the ground lamb, onion, garlic, parsley, cumin, paprika, coriander, cinnamon, salt, and pepper. Mix well until all ingredients are evenly distributed.
Shape the Koftas: Divide the mixture into 12 equal portions. Shape each portion into a long, oval shape around pre-soaked wooden skewers or metal skewers.
Make the Pomegranate Glaze: In a small saucepan over medium heat, combine the pomegranate juice, honey, and balsamic vinegar. Stir and bring to a simmer. Reduce heat and continue to simmer until the mixture thickens into a glaze, about 10 minutes.
Prepare the Mint Yogurt: In a small bowl, whisk together Greek yogurt, chopped mint, olive oil, lemon juice, and salt. Set aside in the refrigerator to chill and let the flavors meld.
Grill the Koftas: Preheat the grill to medium-high heat. Brush the koftas with olive oil and place on the grill. Cook for 6 to 7 minutes on each side, or until fully cooked through and nicely charred on the outside.
Glaze the Koftas: During the last 2 minutes of grilling, brush the koftas generously with the pomegranate glaze, turning to coat all sides.
Serve: Remove the koftas from the grill and let them rest for a couple of minutes. Serve hot with the chilled mint yogurt on the side.
