Stage 1: Create the Kofta Mixture

1. Prepare the Onion: Grate the onion on the coarse side of a box grater into a bowl. Transfer the grated onion to a clean kitchen towel or a few layers of paper towels and squeeze out as much excess liquid as possible. This step is crucial for preventing the kofta mixture from being too wet. Discard the liquid.

2. Combine Ingredients: In a large bowl, add the ground chicken, the squeezed grated onion, minced garlic, chopped parsley, chopped cilantro, olive oil, salt, cumin, coriander, smoked paprika, black pepper, cinnamon, and cayenne pepper.

3. Mix Gently but Thoroughly: Using your hands, gently mix all the ingredients together until they are just combined. Be careful not to overmix, as this can make the kofta tough. The goal is to evenly distribute the herbs and spices without compacting the meat too much.

Stage 2: The Crucial Chilling Period

1. Chill the Mixture: Cover the bowl with plastic wrap and refrigerate for at least 1 hour, or up to 4 hours. Do not skip this step! Chilling allows the flavors to meld together and, more importantly, firms up the mixture, which makes it much easier to shape and helps it adhere to the skewers during grilling.

Stage 3: Shape the Kofta

1. Prepare Skewers: If using wooden skewers, make sure they have been soaked in water. This prevents them from burning on the grill.

2. Shape onto Skewers: Lightly wet your hands with cold water to prevent the mixture from sticking. Divide the chilled chicken mixture into 6 or 8 equal portions. Take one portion and form it into a long, sausage-like shape around a skewer, pressing firmly so it adheres well. The kofta should be about 1-inch thick and 5-6 inches long. Repeat with the remaining mixture and skewers.

3. The Double Skewer Trick (Optional): For extra stability and to prevent the kofta from spinning when you flip them, you can use two parallel skewers for each kofta.

Stage 4: Grill to Perfection

1. Preheat the Grill: Preheat your gas or charcoal grill to medium-high heat (about 400-450°F or 200-230°C). Clean the grates well and lightly oil them with a paper towel dipped in vegetable oil.

2. Grill the Kofta: Place the kofta kebabs on the hot grill. Cook for about 10-12 minutes, turning them every 3-4 minutes, until they are golden brown, lightly charred, and cooked through. The internal temperature should reach 165°F (74°C) on an instant-read thermometer.

3. Rest and Serve: Remove the kebabs from the grill and let them rest on a platter for 5 minutes. This allows the juices to redistribute, ensuring a moist and tender kofta. Serve immediately.
