This is the easiest recipe I have, and also the one I'm the most frightened to try myself. It's a salty, sour, iced yogurt drink from central Turkey. Supposedly, it goes very nice with roasted meats, but as I said, I haven't tried it yet. Perhaps you will! If you do, drop me a line to let me know your experience!
300 ml (1/25 cups) yogurt, preferably natural, definitely unsweetened
250 ml (1 cup) ice cold water
salt, around 1/4 tsp (1.5 ml)
Add ingredients to a blender.
Add additional salt, if needed.
