01 - In a large mixing bowl, whisk together yogurt, olive oil, lemon juice, minced garlic, cumin, coriander, paprika, turmeric, cinnamon, cayenne pepper, salt, and black pepper. Add chicken thighs and ensure each piece is coated thoroughly. Cover and refrigerate for at least one hour or up to overnight for optimal flavor infusion.
02 - In a food processor, pulse garlic cloves and salt until finely minced. With the machine running, slowly drizzle in the oil in a thin, steady stream, alternating with lemon juice, until a smooth, fluffy emulsion forms. If necessary, add ice water one tablespoon at a time for a creamy texture. Adjust seasoning with additional salt or lemon juice to taste.
03 - Preheat grill, grill pan, or skillet over medium-high heat. Remove marinated chicken, allowing excess mixture to drip off. Grill or sear chicken for five to seven minutes per side, achieving full doneness and slight charring. Allow chicken to rest for five minutes before slicing thinly against the grain.
04 - Warm pita bread or flatbreads. Arrange sliced chicken inside, spoon over garlic sauce, and garnish with sliced tomato, cucumber, red onion, and fresh herbs as desired.
