Sumac might not be a common ingredient in every household, but it is worth seeking out for its unique tangy and slightly citrusy flavor.

Ingredients For Tomato Salad With Onion And Sumac
Tomatoes: Fresh and juicy, these form the base of the salad.
Red onion: Adds a sharp and slightly sweet flavor to the salad.
Sumac: A tangy spice that gives the salad a unique citrusy note.
Olive oil: Adds richness and helps meld the flavors together.
Salt: Enhances the flavors of all the ingredients.
Black pepper: Adds a bit of heat and depth to the salad.
Technique Tip for This Salad
To enhance the flavor of the tomatoes, consider using a mix of different varieties such as heirloom or cherry tomatoes. This will add a range of textures and sweetness to the salad. Additionally, after slicing the red onion, soak it in cold water for about 10 minutes to reduce its sharpness and make it more palatable. When adding the sumac, make sure to sprinkle it evenly over the salad to ensure a consistent tangy flavor throughout. Finally, use a high-quality olive oil to bring out the best in the other ingredients.

How to Store or Freeze This Salad
- To store your tomato salad with onion and sumac, transfer it to an airtight container. This will help maintain its freshness and prevent any unwanted odors from seeping in.
- Place the container in the refrigerator. The salad will stay fresh for up to 2-3 days. The tomatoes might release some juice, so give it a quick toss before serving.
- If you want to prepare the salad ahead of time, consider storing the dressing (olive oil, sumac, salt, and black pepper) separately. Combine everything just before serving to keep the vegetables crisp.
- Freezing this salad is not recommended. The texture of the tomatoes and onions will become mushy upon thawing, which can affect the overall quality and taste.
- If you have leftovers and still wish to freeze, consider blending the salad into a sauce or soup. This way, you can preserve the flavors without compromising the texture.
- When ready to use the frozen mixture, thaw it in the refrigerator overnight. Reheat gently on the stove if using as a sauce or soup.
How to Reheat Leftovers
- Gently warm the tomato salad in a skillet over low heat. Stir occasionally to ensure even heating without cooking the tomatoes and onions too much.
- Place the salad in a microwave-safe dish, cover it with a microwave-safe lid or plastic wrap, and heat on low power for 30-second intervals. Stir between intervals to distribute the heat evenly.
- For a slightly different approach, spread the salad on a baking sheet and warm it in a preheated oven at 200°F (93°C) for about 5-10 minutes. This method helps to maintain the texture of the vegetables.
- If you prefer a room temperature salad, simply let it sit out for about 30 minutes before serving. This allows the olive oil and sumac to meld with the tomatoes and onions without applying direct heat.
