One Small Recipe

One of my own favorite vodka based drinks originated in pre-Khomeni Iran. Known as "abdug" the drink is made by mixing equal quantities of soda water and plain yoghurt in a tall glass. Pour in a measure of vodka, place a pinch of salt on the surface and then add a sprig or two of mint. As unlikely as the combi- nation may sound, I recommend it as delicous and highly refreshing.
