At first glance, it might seem like these two condiments are the same thing. They are both seasoned, yogurt-based sauces featuring fresh cucumber. Don’t be fooled — although they are similar, they have a few key differences.  Tzatziki is a classic Greek condiment made with Greek yogurt, fresh cucumbers, garlic, lemon, and dill. It has a thick consistency and the ingredients in any tzatziki recipe do not tend to vary much.  Cucumber raita, on the other hand, has its origins in India. It is made with regular yogurt (or thinned Greek yogurt), fresh cucumbers, cumin, and salt, making it thinner and simpler than its Mediterranean cousin.  Furthermore, cucumber raita belongs to a larger family of raita recipes that are popular throughout India. These yogurt-based sauces can contain a wide variety of different fruits, vegetables, herbs, and spices.
