Preheat the oven to 350F (180C).
Roll the large part of the dough into a 12-inch circle over a clean work surface dusted with flour.
Fold the dough in half.
Fold the dough in half again. You should have a triangle shape.
Gently lift the folded dough and place it over the pan so the pointy end is at the center of the pan.
Unfold the dough, and use your fingers to gently press it into the sides of the pan.
Spread the strawberry preserves evenly over the dough.
Roll the second part of the dough into a 9-inch circle, and use a sharp knife to cut the dough into one-inch strips.
Place half of the strips over the strawberry filling diagonally.
Place the rest of the strips over the top in an opposite direction to the first layer of strips.
Brush with the beaten egg, sprinkle with the almonds, place the pan over a baking sheet and bake for 35-45 minutes over the second lower oven rack.
