The main ingredient in a traditional Greek tzatziki is yogurt. This refreshing sauce or dip is typically made with thick, strained yogurt, often mixed with grated cucumber, garlic, olive oil, lemon juice, salt, and herbs like dill or mint. Tzatziki is commonly served as a condiment with grilled meats, pita bread, or as part of a meze platter. The dish reflects the Mediterranean diet's emphasis on fresh, simple ingredients that enhance flavor while providing nutritional benefits. Its creamy texture and tangy taste make tzatziki a popular accompaniment in Greek cuisine and beyond, often enjoyed during warm weather or festive gatherings.
