Mast-o-Khiar is a Persian Yogurt and Cucumber Dip. It comes together quickly and is customizable based on individual tastes. I made a basic version with cucumbers, yogurt, and dried mint. I garnished it with more dried mint and walnuts. Other possibilities include dried rose petals, garlic or garlic powder, fresh mint, and/or raisins. I served this Mast-o-Khiar with roasted chicken and flat bread.
I used a thick, whole plain yogurt. If your yogurt is more watery, drain it for about an hour in a cheesecloth or a coffee filter set over a sieve. Greek yogurt would also work well. My cucumber had a thicker skin so I peeled it. You can leave it unpeeled based on preference.
