Swedish Gingerbread House

Preheat oven to 350 degrees. On a lightly floured surface, roll out gingerbread dough to about 1/8 inch thick. Chill until firm, about 1 hour. Lightly dust top of dough with flour. Place templates on top and cut out shapes with a paring knife. (Use a small utility knife to cut out the windows.) Transfer shapes to parchment-lined baking sheets. Bake, rotating sheets halfway through, until just beginning to brown, about 15 minutes. Let cool completely.

Make caramel syrup, and assemble house.

Place royal icing in a pastry bag fitted with a medium plain tip (No. 5 or 6). Pipe to outline windows, doorway, and edges of chimney, including top and base. Outline the four joining points of house, sides, and top of roof. Decorate roof: Starting at the top, pipe a horizontal line of icing in a scallop pattern, making curves in even intervals; pipe another scalloped line so the peaks join the scallops above them in the middle. Pipe icicles around edges. Dust roof with confectioners' sugar.
