Wild thyme in Arabic is zaatar (za'atar) but the term is commonly used for a Middle Eastern spice mixture that combines the wild thyme with sumac and toasted sesame seeds. Other ingredients may appear in the mixture as well including ground nuts and other toasted seeds.
Zaatar is used atop of labneh (yogurt cheese) and it's also commonly used to flavor fried eggs. Sometimes the seasoning is added to olive oil and used as a dipping sauce. In Jordan, zaatar is a popular condiment used to season fried and barbecued meats.
Use it for a rub on pork chops: Season thick pork chops with zaatar, salt and pepper. Fry in a hot pan with about 1 1/2 tablespoons of oil until chops are dark brown, about 5 minutes. Turn the chops over. Bake in the oven until chops reach 140F.
You can purchase zaatar in Middle Eastern markets, here Gourmetsleuth (see buy link) or, of course, on Amazon.com: Traditional Lebanese Zaatar.
The ingredients for commercially sold Zaatar will vary per brand. Ingredients include: Thyme, toasted wheat, toasted mixed spices, vegetable oil, salt, toasted sesame seeds, sumak.
