Greek Yogurt: The Heart of Tzatziki
While a variety of ingredients contribute to the distinct flavor of tzatziki, the unquestionable star is the thick, strained Greek yogurt. The quality of the yogurt dictates the overall texture, richness, and probiotic content of the finished dip. In authentic Greek versions, this is traditionally a full-fat yogurt made from sheep or goat's milk, but readily available cow's milk Greek yogurt is a common and excellent substitute.
Why Greek Yogurt is Crucial
Strained yogurt is the foundation of tzatziki, and here’s why:
- Consistency: Regular yogurt contains more whey, the liquid component of milk. Straining the yogurt removes this excess liquid, resulting in a thick, rich base that won't become watery when mixed with other ingredients like cucumber.
- Tang: The fermentation process for Greek yogurt gives it a characteristic tangy flavor that provides a perfect counterpoint to the cooling cucumber and pungent garlic.
- Protein: Being more concentrated than regular yogurt, Greek yogurt is packed with more protein. This helps make the dip a satisfying, hunger-reducing addition to any meal.
The Supporting Cast of Ingredients
While the yogurt is the main ingredient, tzatziki wouldn't be the same without its essential supporting components. Each element plays a crucial role in creating the dip's balanced flavor profile and refreshing quality.
Key ingredients and their purpose:
- Cucumber: This vegetable provides a fresh, cooling flavor and a slight crunch. It must be grated and drained thoroughly to prevent the finished sauce from becoming watery. English or Persian cucumbers are often preferred due to their thin skin and minimal seeds.
- Garlic: Finely minced or grated garlic provides a spicy, savory kick. The amount can be adjusted based on preference, from a subtle hint to a more pronounced, pungent bite.
- Extra Virgin Olive Oil: A good quality olive oil adds richness and a smooth texture, harmonizing the different flavors.
- Fresh Herbs: Fresh dill is the most traditional herb used in Greek tzatziki, though mint is sometimes used as a variation. The herbs add a vibrant, grassy note that enhances the freshness of the dip.
- Vinegar or Lemon Juice: A touch of acidity, traditionally from red wine vinegar, brightens the overall flavor. Lemon juice is a common alternative that provides a zestier taste.

Frequently Asked Questions
Q: What type of yogurt is best for making tzatziki? A: Thick, plain, full-fat Greek yogurt is best. Its strained nature gives the dip a creamy, rich consistency that won't become runny.
Q: Do I have to use Greek yogurt? A: You can use regular plain yogurt, but it should be strained first using cheesecloth to remove excess whey and achieve the desired thickness. Some recipes also use sour cream for a variation.
Q: How do you prevent tzatziki from getting watery? A: The key is to remove as much moisture as possible from the grated cucumber. After grating, place it in a cheesecloth or towel and squeeze it dry before adding it to the yogurt.
Q: What kind of cucumber should I use for tzatziki? A: English or Persian cucumbers are ideal because they have thinner skins and fewer, smaller seeds, reducing the risk of a watery texture. If using regular cucumbers, peel them and scrape out the seeds first.
