Achari Chicken Tikka is a popular Indian appetizer made with marinated chicken pieces cooked in a tandoor or grill. The chicken is marinated in a flavorful blend of spices, yogurt, and pickling spices like mustard seeds, fenugreek seeds, and fennel seeds. The result is a juicy and tangy chicken tikka with a hint of pickle-like flavor. It is perfect for parties or as a starter for a meal.
