   2      pints         plain yogurt
   6      tablespoons   sugar
   2      ounces        pistachio nuts -- chopped

Preparation:

Put yogurt into a large piece of cheesecloth. Tie like a bag. Hang over a bowl overnight so that the excess liquid drips off. Stir in the sugar, and chill. Garnish with the chopped pistachios. For a spicier version: Add 1/4 tsp powdered saffron and/or 3/4 tsp ground cardamom.
