The best construction gingerbread house recipe. Super strong, no spread, great for cutting intricate templates, and holds up for the entire holiday season. One batch makes three individual houses.
Sift together the flour, cinnamon, ginger, nutmeg, cloves, and salt. Set aside.
Melt the vegetable shortening until just liquid (not hot). In your stand mixer, combine the melted shortening, sugar, and molasses and mix until smooth. Add the egg and mix to combine.
Switch to the paddle attachment, add your dry ingredients, and mix on medium-low until a smooth, firm dough forms. Do not overmix.
Divide the dough in half and roll each half out to ¼ inch thick directly onto a silicone baking mat (this is important if you're doing sugar windows later). Try to keep the thickness as even as possible for even baking. Pop the rolled dough in the freezer for 20 minutes. This makes it much easier to cut cleanly.
Place your templates on the chilled dough and cut around them. An X-Acto knife works great for clean edges, but any small sharp knife will do. Just be careful not to cut through your silicone mat. Peel away the excess dough and save it to re-roll for more houses.
NOW is the time to add a brick texture, a roof shingle pattern, or any other embossing BEFORE you bake. Press your impression tool firmly into the raw dough. A spoon can make scalloped roof tiles. The blunt side of a butter knife makes great brick lines.
Bake at 300º F for 30 to 50 minutes. You're looking for very firm, dried-out pieces that have darkened slightly. If they feel even a tiny bit soft or bendy, keep baking. Under-baked pieces will flex and crack during assembly. Keep an eye on the color, especially on smaller pieces like chimneys which bake faster.
Let the pieces cool fully on the mat or pan before you touch them. Once cool, set them aside uncovered overnight to dry out further. The drier they are, the stronger your assembly will be.
Royal Icing
Make sure your mixer bowl, whisk, and all tools are completely grease-free.
Combine sifted powdered sugar, egg whites, and cream of tartar in the mixer bowl. Mix on low to combine, then increase to high and whip until bright white and stiff, 1 to 2 minutes. Add vanilla and mix briefly.
Keep covered with plastic wrap pressed to the surface or a damp towel at all times to prevent crusting.
Assembly
Choose and prepare your base. Pipe a ring of royal icing on the base where the house will sit.
Pipe a generous line of thick royal icing along the edges of your front piece. Press a side wall into place, hold for 30 to 60 seconds, then support with tin cans. Repeat with remaining walls.
Let walls set for at least 1 hour with tin can support before adding the roof.
Pipe icing along the top edges of the walls. Press roof pieces into place and support with cans. Let the fully assembled house set overnight before decorating.
Decorate with colored royal icing and assorted candies. Let everything dry fully before moving.

Notes
Ingredient notes: Use sugar-free hard candies or pre-cooked isomalt for the windows, since they stay clearer than regular sugar candy over time.Pan options: This dough is rolled and baked directly on a silicone baking mat rather than in a pan, so pan size doesn't apply here. Any rimless baking sheet that fits under your mat will work; there's no need to adjust the bake time for equipment size.Make-ahead and storage: Baked pieces: room temperature airtight container up to 1 week, or frozen up to 3 months. Dough: refrigerator up to 3 days. Assembled structure: can be built a day ahead before decorating. Display the finished house in a cool, dry place away from direct sunlight; construction gingerbread made with shortening can last the entire holiday season and potentially years if stored carefully.Substitutions: Molasses can be replaced with an equal weight (not volume) of dark corn syrup, honey, maple syrup, or dissolved brown sugar. Butter can be substituted 1:1 for the shortening for a more edible result, but the pieces will be slightly softer and won't last as long on display.Critical do-nots: Don't use any bowl, whisk, or tool with grease on it for the royal icing. It will not set hard. Don't add the roof until the walls have set for at least an hour with tin can support. Don't decorate or move the assembled house until it's had a full overnight to cure.
