6: Then roll the dough up. This is the trickiest part of the recipe. You can use a palette knife to help you, as shown in the photo, or slip a sheet of paper under the dough to help you lift it up.
7: Roll up tightly and seal the roll by brushing only the trailing edge with beaten egg to help it stick.
8: Place the roll with the seam underneath on a baking sheet and put in the freezer for 30 minutes. This is to firm up the dough and make it easier to cut.
9: After this "firming" time, cut the dough into slices 1 to 1.5 cm (1/4 to 1/2 inch) thick.
10: Arrange on the baking sheet with room between them, as they need room to expand.
