Turkish Sumac Onions, also known as Marinated Onion Salad, is a vibrant and tangy dish that adds a refreshing touch to grilled meats and kebabs.

Commonly used in Middle Eastern and Mediterranean cuisines, sumac is often sprinkled over salads, grilled meats, and rice dishes. Its slightly tart and citrusy profile makes it an essential ingredient in Turkish Sumac Onions, providing a refreshing contrast to the sweetness of pomegranate syrup and the sharpness of raw onions.
