In a food processor, put 2 cups of sour cream plus everything else except pita bread and combine.
Warm 5 pitas on the stove top burner.
Pour the sour cream herb mixture into a large bowl. Rip bits of the pita and drop it in, stirring to cover the bread.
Put in the fridge for some time. As the bread absorbs the moisture, you may need to add more sour cream & water. Mix the sour cream/water in a small bowl, then add to the Shafuut.
Eat as is, or with Sahwk (a spicy tomato, chili, garlic herb condiment, made fresh. See below.
