Is tzatziki made from yogurt or sour cream? The Traditional vs. Modern Debate

The word 'tzatziki' is a loanword from Turkish, with roots in yogurt-based dips from Central Asia. This beloved Mediterranean sauce is traditionally crafted with strained yogurt, yet many home cooks and restaurant chefs wonder: is tzatziki made from yogurt or sour cream?

Quick Summary

Traditional tzatziki relies on strained yogurt, like Greek yogurt, for its signature creamy base, while sour cream is a modern and less tangy substitute used in various recipes. The choice of base significantly impacts the dip's flavor, texture, and nutritional content, with yogurt offering a lighter, higher-protein option.

Key Points

• Traditional Base: Authentic Greek tzatziki is made from thick, strained yogurt, traditionally from sheep or goat's milk, or full-fat Greek yogurt as a common substitute.

• Modern Substitute: Sour cream is a modern, non-traditional base for tzatziki, valued for its richness and smoother texture without the need for straining.

• Nutritional Difference: Greek yogurt-based tzatziki is typically higher in protein, lower in fat, and contains beneficial probiotics, making it a healthier option.

• Flavor Profile: Yogurt provides a characteristic tangy and refreshing flavor, while sour cream offers a milder, richer taste profile.

• Crucial Preparation: The most important step for both versions is thoroughly draining the grated cucumber to prevent a watery consistency in the final dip.

• Best Choice Depends: The ideal base depends on personal preference for taste and texture, as well as dietary considerations such as calorie, fat, and protein content.

The Origins and Traditional Foundation: Strained Yogurt

Authentic tzatziki is unequivocally made with yogurt, specifically a thick, strained variety. The traditional Greek version often uses sheep or goat's milk yogurt, but full-fat Greek yogurt is the most common and accessible substitute for achieving the right consistency. The key to authentic texture is to remove as much moisture as possible, both from the yogurt and the cucumber. Using a cheesecloth or fine-mesh sieve to strain the yogurt for several hours or even overnight is a crucial step that ensures a creamy, non-watery final product.

Besides the base, traditional tzatziki includes several other key ingredients that create its fresh and complex flavor profile. Grated cucumber is carefully drained of its excess liquid to prevent dilution. Fresh garlic adds a pungent kick, while dill and occasionally mint provide aromatic freshness. A splash of vinegar or lemon juice and a drizzle of extra virgin olive oil round out the classic preparation. These ingredients combine to create a dip that is not only rich and tangy but also cooling and refreshing, making it a perfect accompaniment to grilled meats like souvlaki or served as part of a mezze platter with pita bread. The meticulous preparation of draining the ingredients is what sets a truly authentic tzatziki apart from its less-thickened relatives.

The Rise of the Modern Variation: Sour Cream

While yogurt is the traditional base, modern culinary adaptations sometimes substitute or combine it with sour cream. This practice has become common for a few reasons, including convenience and a different flavor preference. Sour cream offers a rich, smooth, and naturally thick consistency that doesn't require the straining process of traditional yogurt. Its flavor is also milder and less tangy than Greek yogurt, which some prefer.

Recipes calling for sour cream may use it exclusively or blend it with Greek yogurt to balance the creaminess and tang. This can result in a dip that is richer and fattier than its traditional counterpart. For those following a keto diet, a sour cream-based tzatziki may be preferred, as sour cream typically has lower carbohydrate content than yogurt. When using sour cream, the preparation is often simpler, but the final taste and nutritional value will differ from the authentic version. The addition of fresh herbs, garlic, and cucumber remains essential for the signature tzatziki flavor, regardless of the base.

The Nutritional Advantages of Yogurt-Based Tzatziki

Choosing to make tzatziki with Greek yogurt comes with a host of nutritional benefits. The Greek yogurt base is not only lower in fat and calories than sour cream, but it is also packed with protein and probiotics. These properties make it a smart addition to a balanced diet.

• Weight Management: The high protein content and lower calorie count make it a filling and satisfying condiment that can assist with weight management.

A Simple Recipe for Authentic Greek Tzatziki

Creating your own authentic yogurt-based tzatziki is a straightforward process that yields incredibly fresh and vibrant results. The key is in the preparation of the main ingredients to avoid a watery dip.

Ingredients:

• 2 cups full-fat Greek yogurt
• 1 large cucumber, peeled, seeded, and grated
• 2 cloves garlic, finely minced or grated
• 1-2 tablespoons extra virgin olive oil
• 1 tablespoon white wine vinegar
• 2 tablespoons fresh dill, finely chopped
• Salt and white pepper to taste

Instructions:

1. Prepare the Cucumber: Grate the cucumber and place it in a fine-mesh sieve or a cheesecloth-lined bowl. Sprinkle with a pinch of salt to draw out excess moisture. Let it sit for at least 30 minutes, then squeeze out as much liquid as possible.
2. Strain the Yogurt (Optional): For an even thicker consistency, place the Greek yogurt in a coffee filter-lined sieve over a bowl and refrigerate for a couple of hours or overnight to drain excess whey.
3. Combine Ingredients: In a medium-sized bowl, combine the strained yogurt, drained cucumber, minced garlic, olive oil, and white wine vinegar. Stir until well combined.
4. Add Herbs and Seasoning: Fold in the fresh dill and season with salt and white pepper to taste. Adjust the ingredients as needed for your desired flavor profile.
5. Chill and Serve: Refrigerate the tzatziki for at least one hour before serving. This allows the flavors to meld and deepen, resulting in the best possible taste and texture.
