Step‑by‑Step Instructions for Sumac Onions
Step 1: Combine Ingredients
In a large mixing bowl, toss together the sliced red onions and chopped fresh parsley. Sprinkle in 2 tablespoons of sumac, followed by 2 tablespoons of red wine vinegar and a drizzle of extra virgin olive oil. Add a generous pinch of kosher salt. Using your hands, massage the mixture gently for about 2 minutes until ingredients are well-combined and the onions begin to soften slightly, releasing their juices.
Step 2: Marinate the Mixture
Cover the bowl with plastic wrap or a lid, allowing the sumac onions to marinate for about 20 minutes at room temperature. This resting period allows the onions to absorb the vibrant flavors of the sumac and vinegar, while the texture transforms into a tender yet crunchy delight. You’ll notice the onions take on a glossy appearance as they mingle with the dressing.
Step 3: Adjust Seasoning
After the marinating time elapsed, taste the sumac onions and adjust seasoning if necessary. If desired, add an extra pinch of salt or more sumac to enhance the tanginess. Toss everything together again for an even distribution of flavors, ensuring your sumac onions are perfectly seasoned and ready to elevate your meal.
Step 4: Serve and Enjoy
Once seasoned, transfer the sumac onions to a serving dish. They are now ready to serve as a fresh condiment that can brighten up grilled meats, sandwiches, or even grain bowls. For an appealing presentation, garnish with a sprinkle of extra parsley or a few more sumac flakes to highlight their vibrant colors.
