A work colleague mentioned that making gingerbread houses at this time of the year was a thing in Sweden (and elsewhere?). She sent me a photo. This inspired Mr14 to google instructions and set to work.
The dough was made on day 1, rested for hours in the fridge, rolled out and cut carefully according to the carefully sketched out plan. Then the pieces were rested in the fridge before baking. This was a day's work.
The mortar for the house was made on day 2 using icing sugar and egg whites.
Construction required support from the pantry and patience waiting for the mortar to set for each part of the build.
The mortar then became part of the decoration with the aid of smarties and liquorice bullets.
The finished gingerbread house was admired and then eaten.
