The Middle East is no stranger to strife, and its kitchens are nearly as contentious as its borders. The catalyst for all the culinary unrest? A regional spice blend called za'atar. The exact formulation varies across countries—nay, each household even—and each believes its recipe to be superior.

We here at Guy Gourmet take a more moderate stance: I've never encountered za'atar I didn't like, and I've yet to encounter a dish that didn't benefit from its addition.

So what exactly is this wonder ingredient? Za'atar is a blend of sumac, sesame seeds, thyme, and salt, with cumin, oregano, and other spices occasionally being included as well. Earthy, savory, and tremendously aromatic, it’s responsible for much of the pervasive, iconic flavor associated Mediterranean food.

True purists craft their own, but packaged blends are readily available online or at Mediterranean specialty shops, and many mainstream grocers, including Whole Foods, carry it as well. Oh, and before you hit the store? It's pronounced "zAH-tahr," with no nasal "aeh" inflection. (Remember: It's a spice, not a strep culture.)

Now, chances are, you've already experienced this transformative ingredient; you just might not have been able to identify it. You know the ultra-authentic, luxuriant hummus that makes the store-bought stuff taste like reconstituted gerbil food? Teeming with za'atar. Or how about the vibrant, flavor-dense Greek salads you can never seem to recreate once home? Positively brimming with it. But traditional applications are just the beginning—this versatile ingredient works far beyond Mediterranean waters. Here are a few more options:

These are just a few ideas to get you started. Give them a shot or come up with your own. Either way, clear some space on your spice rack—this is one ingredient you'll want to keep close at hand.
