Mix yogurt, water, and salt to taste (I pinch) in a cocktail shaker. Stir ingredients with a fork or spoon until mixed.
1
Seal by closing the shaker and pressing firmly on top. Shake hard for 10 seconds to aerate the mixture.Turn the shaker to grasp the bigger side.
2
Open the lid carefully (you may need to smack the side with your palm). Add a handful of ice, seal, and shake again. Put forth the effort! You want maximum foam.
