How to Make It
Heat oven to 350° F. In a small bowl, combine the sugar and cinnamon; set aside.
Brush the pastry sheets with the eggs and sprinkle with the cinnamon-sugar mixture. Cut each sheet of pastry crosswise into ¾-inch strips. Halve the strips crosswise.
Twist each strip. Place on parchment-lined baking sheets, spacing them 1½ inches apart. Bake until golden and crisp, 12 to 15 minutes. Cool slightly on baking sheets, then transfer to wire racks to cool completely.
Keep at room temperature in an airtight container for up to 1 week.
