How to Make It
Preheat oven to 400°F. Line 2 baking sheets with parchment paper. Transfer puff pastry sheet to a lightly floured work surface; roll into a 16- x 10-inch rectangle (about 1/8 inch thick). Brush dough lightly with egg; reserve remaining egg. Sprinkle Cheddar, chile powder, salt, pepper, onion powder, and garlic powder over 1 long half of dough rectangle. Fold empty dough half over cheese mixture; press gently. Cut dough crosswise into 32 (5- x 1/2-inch) strips. Transfer to prepared baking sheets.
Working with 1 strip at a time, brush both sides lightly with reserved egg. Twist and gently stretch each strip to about 7 inches long. Bake in preheated oven until golden, 14 to 16 minutes, rotating baking sheets halfway through bake time. Transfer to a wire rack to cool completely, 15 minutes.
