Step 1

Pre-heat your oven to 400°F (205°C) with a rack in the middle. Line up two baking sheets with parchment paper.

Step 2

Step 1 – Unfold your puff pastry sheet on a working surface. Roll out the pastry lightly with a rolling pin to smooth out the folds/creases and to reach a square of roughly 18"x18" (45.5cmx45.5cm) and about 1/8-inch in thickness.

Step 3

Step 2 – Sprinkle the grated cheese and 1 teaspoon black pepper in an even layer over the right half of the sheet, and leaving a 1-inch border on the right edge. Brush ½ tbsp milk onto the border. Fold the left side of the pastry over the right cheesy half and press onto border to seal.

Step 4

Step 3 – Mix egg yolk with remaining ½ tbsp milk, and brush this egg wash onto the top of the pastry. Sprinkle with remaining black pepper and the sea salt flakes.

Step 5

Step 4 – Cut the pastry into ½ inch (1.25cm) wide strips, using a pizza cutter or very sharp knife. Hold strips by each end and twist (about 5-6 turns per strip). Transfer twisted strips onto prepared baking sheets.

Step 6

Step 5 – Bake each sheet for 12-14 minutes, until twists are crisp and golden. Serve immediately.
