Red onions are sharper and sweeter than the other onion varieties, which makes them a popular choice for raw preparations such as salads or pickling. In addition they are rich in antioxidants and antibacterial properties and also help improve gut health by aiding in digestion.
Cut them into halves and soak them in water as you prepare other ingredients to reduce the pungency and prevent teary eyes.

Sumac Onions
If you have ever dined at a Turkish or Middle Eastern restaurant and ordered kebabs, you would likely have noticed chicken and meat kebabs served with a side of onion salad.
Sumac onions or onions with sumac are made by pickling sliced red onions in a marinade, typically consisting of sumac and lemon juice. The sumac gives the onions a zingy flavor and adds a distinctive reddish color.
Sumac onions are often used as a topping or accompaniment in various dishes, such as salads, sandwiches, kebabs, grilled meats, and wraps.
What is Sumac?
Sumac is a spice native to the Middle Eastern and Mediterranean region. It is made by drying and coarsely grinding the berries of the Sumac plant.

The spice has a tangy lemon-like flavor and dark red color, which make it a versatile ingredient for enhancing the taste and color of various dishes, including salads, marinades, and dips.
Sumac can be found in grocery stores and supermarkets with Middle Eastern or Mediterranean ingredients. You can even purchase it from online retailers. I got mine from Amazon.

The Ingredients

Sumac: is the key ingredient that gives the recipe its distinct flavor. So it should not be substituted.
Red onions: red onions are the best for this salad.
Parsley: Freshly chopped parsley adds a pop of green color and provides a refreshing balance to the recipe.
Lemon juice: fresh lemon juice adds more depth of flavor to the dish.
Red chili flakes: to add a hint of spice to the dish. Alternatively, crushed peppercorns or sliced fresh chili would also work. You can even omit it if you wish.

Olive oil: adds some richness to the dish. Use high-quality extra virgin olive oil.

How to make Sumac Onions
- To prepare the onions, peel and cut the onions into halves. Slice the onions thinly using a sharp knife or a mandoline slicer for even slices. Transfer the sliced onions to a large bowl.

- Finely chop parsley and put them in the same bowl.

- Add sumac, salt, red chili flakes, lemon juice, and olive oil. Mix everything.
