Just so you remember for next year: gingerbread houses make great Christmas presents and can be made at a very low cost using no gas or electricity. You just need to walk over to places like Aldi or Lidl in November/December and get
– a huge bag of cheap gingerbread or other suitable Christmas biscuits
– icing sugar and either lemon juice (or any kind of juice) or water (I know people who have made gingerbread house icing with spiced water or spice tea)
– bright edible decoration such as smarties or other colourful junk
– some kind of support beams or things for the gingerbread
Make a very thick icing from the icing sugar and the accompanying liquid.
Build a house (as stable as possible) from the gingerbread/biscuits and the icing sugar using objects to support the construction if necessary (the best thing is to fill the house with cookies so that the walls/roof don’t collapse).
Decorate the house and wait for it to dry.
