Construction Grade Gingerbread House Recipe

1. For the Dough: Trim a sheet of parchment paper to fit the interior of a half sheet pan. Adjust oven rack to lower-middle position and preheat to 350°F (175°C). Combine brown sugar, cinnamon, ginger, cloves, salt, corn syrup, butter, and vanilla in the bowl of a stand mixer fitted with a paddle attachment. Mix on low until smooth, then sprinkle in flour and continue mixing to form a stiff dough. Turn onto a lightly floured surface and knead until smooth. Proceed immediately, or wrap in plastic and set aside at room temperature until needed, up to 24 hours. (Larger batches should be divided into 14-ounce portions.)

1. In the bowl of a stand mixer fitted with a paddle attachment, combine egg white with half the powdered sugar. Mix at low speed until sugar disappears into a paste, then gradually sprinkle in the rest. Increase speed to medium and beat until smooth and light, about 2 minutes. If too stiff, thin icing with a few drops of water. Use immediately; keep covered tightly in plastic to prevent icing from drying in bowl. Royal icing can be kept in an airtight container at room temperature up to 12 hours.
