The primary ingredient in traditional tzatziki is yogurt, specifically strained Greek yogurt, which gives the dish its creamy texture and tangy flavor. Tzatziki is a popular sauce or dip in Mediterranean and Middle Eastern cuisines, commonly served with grilled meats, pita bread, or as part of meze platters. Along with yogurt, tzatziki typically includes finely chopped cucumber, garlic, olive oil, vinegar or lemon juice, and fresh herbs, particularly dill or mint. This refreshing condiment not only adds flavor but also provides a cooling effect in spicy dishes, making it a versatile accompaniment in many culinary contexts.
