Tandoori chicken is an Indian dish marinated in yogurt, lemon juice and a mixture of some or all of the following spices: ginger, garlic, cumin, chili powder, coriander, turmeric, cayenne pepper, paprika and garam masala (if you can find it).
The marinated chicken is baked at a high heat using either wood or charcoal in an Indian Tandoor oven, a cylindrical oven made of clay. These ovens are typically used in India for baking many types of bread and also for roasting meat.
