If using plain yogurt, place it in a strainer lined with a paper towel and place the strainer over a bowl. Let the yogurt drain and thicken for 20 minutes.
In a medium bowl, combine the strained or Greek-style yogurt and the rest of the ingredients. Add salt, to taste.
Recipe Analysis Note: Ingredients without discrete measurements such as "Salt, to taste" or "Ice cream, optional" are omitted from analysis. This is because amounts can be highly variable and difficult to determine.
