Call it Greek tzatziki, Turkish cacik, or Indian raita, but to me, it’ll always be mast-o-khiar. It’s part of nearly every Iranian meal and couldn’t be easier to prepare. English translations will often call it a dip, and while it can be (raise your hand if you dipped your potato chips into mast-o-khiar while growing up), it’s really eaten as a side dish alongside a complete meal.
Mast-o-khiar can include variations like dried rose petals (how Persian, I know) or dried shallots (in which case it becomes mast-o-musir), but my favorite is this classic version, garnished with a light sprinkling of walnuts.
2 cups Middle Eastern or Greek-style yogurt, plain
2 or 3 Persian cucumbers, finely chopped or grated
1 small garlic clove, minced
1 1/2 tablespoons ground dried mint
2 tablespoons walnuts, chopped (optional)
salt and pepper to taste
1. Mix all of the ingredients in a bowl, reserving half a tablespoon of walnuts for garnish. Chill and serve cold.
