If you’ve been scrolling through social media lately, you might have noticed an unexpected food trend: thinly sliced red onions dusted with sumac. Food influencers, chefs, and home cooks alike are raving about this simple yet vibrant combination, and it’s popping up everywhere—from TikTok recipes to high-end restaurants. But what exactly is the deal with sumac and onion? Why is this pairing suddenly all the rage? Let’s dive into the flavors, cultural history, and the modern appeal of this trending duo.

The Flavor Explosion: Why Sumac and Onion Work So Well

Red onions have a natural sharpness with a mild sweetness, but when mixed with sumac, they transform into something truly special. Sumac, a spice made from dried and ground berries of the sumac plant, brings a citrusy, slightly tangy flavor that balances the bite of the onion. The result? A refreshing, zesty, and slightly tart condiment that enhances almost any dish it accompanies.

The sumac not only mellows the pungency of the onion but also gives it a beautiful reddish-purple hue, making it as visually appealing as it is delicious. When paired with olive oil and a pinch of salt, the onions become slightly softened, further deepening their flavor and making them even more versatile.

What is Sumac?

Sumac is a spice made from the dried and ground berries of the sumac plant, commonly used in Middle Eastern and Mediterranean cuisines. It has a tangy, citrus-like flavor that adds brightness to dishes without the acidity of lemon juice or vinegar. Sumac is often sprinkled on meats, salads, and dips to enhance flavor and balance richness.

Cultural and Traditional Roots

While this combination is currently experiencing viral popularity, it’s far from new. Sumac and onion have been an essential part of Middle Eastern, Mediterranean, and Central Asian cuisines for centuries.

In Turkish and Persian cuisine, sumac onions are a staple accompaniment to grilled meats, kebabs, and even sandwiches. The acidity of the sumac cuts through the richness of lamb and beef, making every bite feel lighter and more balanced. Similarly, in Lebanese and Syrian food, sumac onions are commonly found in wraps and mezze platters, adding a bright contrast to savory dishes.

Even in parts of India and Pakistan, where sumac itself is less common, onions are often paired with tangy ingredients like lemon juice or vinegar—essentially achieving the same refreshing effect that sumac brings.
