Gingerbread house building

Either works well, depending on your time and goals. Baking from scratch fills the kitchen with spiced gingerbread smell, lets you cut custom-shaped panels, and is more satisfying, but it adds significant time. A kit or shop-bought panels skip straight to the fun assembly and decorating, which is ideal with young children or for a quick festive afternoon. Many families do a kit for ease, then graduate to baking their own once they want bigger or more elaborate houses.

Usually the roof went on before the walls set. Royal icing is only strong once it has dried hard, so adding the heavy roof panels to freshly joined walls makes the whole thing slide and cave under the weight. Build the four walls into a box first, prop them upright with cans or jars, and let the icing set completely, often an hour or more, before adding the roof. Runny or too-thin icing also fails to hold, so keep it stiff.

Royal icing, which acts as both glue and mortar. Made from egg white and icing sugar, it dries hard and rigid, effectively setting like a brittle cement that bonds the gingerbread panels and holds the structure firm. The same icing, slightly looser, is piped on for snow and decoration. Getting its consistency right, stiff for assembly so it does not slide, is essential, and keeping it covered stops it crusting over while you work.

Yes, especially the decorating phase. The structural assembly needs a steady hand and patience for the icing to set, so an adult often handles that part, but once the house is solid, children love piping icing and sticking on sweets, and it suits all ages. Doing the building in advance and bringing children in to decorate is a common approach. Just place the house on a board first, since it cannot be moved safely once built.
