Line a large baking sheet with parchment paper.
Divide the dough into two equal parts. Refrigerate one part while you work with the first part.
Roll the dough into an 18x14-inch rectangle over a lightly floured clean surface.
Spread half of the almond filling over the top half of the dough.
Fold the bottom part of the dough over the top part that.
Gently roll the dough back into a 18x14-inch rectangle.
Use a sharp knife or pizza cutter to make evenly spaced cuts along the wide edge of the dough, leaving a 2-inch gap between each cut.
Use the spaced cuts as a guide to slice the dough into rectangles. Then, cut each rectangle in half diagonally to form triangles.
Gently roll each triangle into a crescent shape, starting from the wide edge and rolling toward the pointed tip.
Place the shaped pastries over the prepared pan leaving 2-inches gap between each pastry.
Brush with the egg, and set a side in a warm spot to rest for about 90 minutes.
Bake at 350F (180C) for 20-25 minutes until golden brown.
Remove from the oven and immediately brush with the syrup. Give it 10-15 minutes to cool, then serve.
