Creating Shish Tawook is straightforward if you follow these easy steps:

1. Prepare the Marinade: In a large bowl, whisk together the yogurt, olive oil, minced garlic, lemon juice, paprika, cumin, coriander, cinnamon, salt, black pepper, and cayenne pepper if using.
2. Cut the Chicken: Cut the chicken breasts into 1-inch cubes for even cooking.
3. Marinate the Chicken: Add the chicken cubes to the marinade, mixing well to ensure each piece is coated. Cover the bowl and refrigerate for at least 1 hour.
4. Prepare the Skewers: If using wooden skewers, soak them in water for about 30 minutes to prevent burning. If using metal skewers, proceed directly to the next step.
5. Skewer the Chicken: Thread the marinated chicken onto the skewers, leaving a little space between each piece for even cooking.
6. Preheat the Grill: Heat your grill to medium-high heat.
7. Grill the Skewers: Place the skewers on the grill and cook for 15-20 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.
8. Check for Doneness: The chicken should reach an internal temperature of 165°F (75°C).
9. Remove and Rest: Once cooked, remove the skewers from the grill and let them rest for a few minutes.
10. Serve: Carefully slide the chicken off the skewers onto a serving platter.

Following these steps will ensure your Shish Tawook is flavorful and perfectly cooked!
