Tzatziki sauce is made from Greek yogurt, garlic, lemon juice, cucumbers and dill, and it is seasoned with salt and pepper. Some other recipes call for sour cream, olive oil and white wine vinegar as well.
To make easy tzatziki, add 1 cup of Greek whole milk yogurt, 1 teaspoon of lemon zest, 1 tablespoon of fresh lemon juice, 1 seeded and grated English cucumber and 2 cloves of minced garlic in a bowl. Season the mixture with 2 tablespoons of chopped fresh dill, and add kosher salt and freshly cracked black pepper to taste. Combine everything well, and chill the dip before serving with cripsy pitas. Enhance the flavor with chopped resh mint or za'atar spice.
Make another tzatziki recipe by seeding and peeling 1 hothouse cucumber, tossing it with 1 tablespoon of kosher salt and chilling it in a sieve so that excess juice can drain out. If not using Greek yogurt, place 1 pint of regular yogurt in a cheesecloth, and allow the liquid to drain out to create a thicker yogurt.
After the cucumber and yogurt drain for three hours, mix the two together, and stir in 1/2 cup of sour cream, 1 tablespoon of white wine or Champagne vinegar, 2 tablespoons of freshly squeezed lemon juice and 1 tablespoon of good olive oil. Season the dip with 1 1/2 teaspoons of minced garlic, 1/2 teaspoon of salt, 1 pinch of freshly ground black pepper and 1 1/2 teaspoons of minced fresh dill. Chill the dip for two hours before serving it.
