Notes
In addition to the cucumbers and onions, you can also add other veggies of your choice to make a nice, wholesome tasty salad. Cherry tomatoes, radish, beet and carrots are all great choices.
Start with a little Sumac and salt, toss everything well and give it a quick taste to check for the right amount of saltiness. You can always add more if needed.
Remember to choose ripe, fresh cucumbers for this salad. Check if they’re firm and don’t have any soft spots before you use them.
Your leftover Sumac cucumber salad can stay good in the refrigerator for 2 days.
Make sure you use an airtight container to store it.
