1 sheet puff pastry, thawed
1/2 cup sesame seeds
1/2 cup grated parmigiano
1 tablespoon aleppo pepper or cayenne
salt & pepper to taste
Preheat oven to 425 degrees F.
On a lightly-floured surface roll out puff pastry to about 50% bigger. Keep to a rectangle shape. Beat the egg with a teaspoon or two of water and brush lightly on the surface of the dough. Sprinkle sesame seeds, parmigiano evenly over the surface. Sprinkle hot pepper (according to taste) evenly and season with salt & pepper.
Using a knife or pizza-cutter, cut dough in half width-wise. Then cut each section lengthwise into 1/2-inch strips.
Line a sheet/baking pan with parchment. Lift each strip and twist it a couple of times then line up on sheet pan twisted. Repeat with the rest of the strips of flavored dough (you'll probably need 2 sheet pans). Bake for about 10-15 minutes until golden. Cool before storing. Breadsticks keep at room temperature, wrapped in foil, for as long as a week.
