The main ingredient in traditional Greek tzatziki is yogurt, particularly strained Greek yogurt. This creamy sauce is a staple in Greek cuisine, offering a refreshing and tangy flavor. Tzatziki is typically enhanced with grated cucumber, garlic, olive oil, vinegar, and various herbs like dill or mint, all contributing to its distinctive taste. It serves as a delicious dip or sauce often paired with grilled meats, pita bread, or fresh vegetables. Its coolness makes it particularly enjoyable during hot weather, embodying the essence of Mediterranean cuisine.
