Puff Pastry Sticks with Cheddar

Ingredients:

• 1 package (500g) frozen puff pastry, thaw in the refrigerator
• 1 large egg
• 1 cup grated sharp cheddar (about 110 g)
• 0.5 cup grated Parmesan (about 30 g)
• Flour, for working with dough

Preparation:

1. Lay the puff pastry sheets out on a lightly floured work surface. Beat the egg with 1 tablespoon of water; generously brush the sheets with the mixture (set the remaining egg aside for later).
2. In a medium bowl, combine the cheddar, Parmesan, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Sprinkle the cheese mixture over 1 sheet of dough, then place another sheet of dough, egg-brushed side down, on top, matching the edges. Lightly flour the dough; press the top sheet firmly, then roll out the rack into a 10x12-inch rectangle.
3. Line 2 baking sheets with parchment paper. Cut the puff pastry rectangle in half lengthwise. Cut each half crosswise into 18 strips. Twist each strip several times and arrange them on the prepared baking sheets, spacing them 1 cm apart. Brush with the remaining beaten egg. Refrigerate for at least 20 minutes and up to 1 day.
4. Position racks in the upper and lower thirds of the oven and preheat the oven to 375°F (190°C). Bake the cheese sticks, rotating the baking sheets halfway through, until puffed and golden brown, 30-35 minutes. Transfer the sticks (on the parchment paper) to a wire rack and let cool completely.
