Mix sourdough starter with next four ingredients, mixing/kneading well. Cover and let rise until doubled.|
Add additional flour. Knead well. Divide dough into three equal parts. Form each into a smooth round ball. Roll each ball to 1/2 inch thickness. Place on nonstick baking sheets and let rise.
Preheat oven to 475°F. The high temperature helps the pockets form. Bake for about 10 minutes, or until puffed up and just starting to turn light brown.
