Roll out 1/4 of the dough at a time, keeping the remaining dough chilled. Roll 1/16 inch thick. Cut in 1 1/2-inch wide strips. Cut diagonally at 4-inch intervals. Make 1 inch slit lengthwise in center of each piece. Slip one end through the slit. Fry a few at a time in deep fat (350 degrees F) for 1 to 2 minutes or until golden. Remove from fat with a slotted spoon. Drain on paper towels. Sprinkle with icing sugar. Store in an airtight container.
