I got some kids in to make Gingerbread houses yesterday! They did an amazing job... I purchased the pre-baked house peices from Ikea - for about $6.50 per house... then just made Royal Icing (480gm pure icing sugar and 2 egg whites) for the cement and decorating! Heaps of lollies were arranged (and eaten) into wells, suns, trees, pergolas, and all sorts of adornments!
Here are the fruits of our labours... ENJOY! (note... handiwork of 2 x 7 year olds, 1 x 6 year old, 2 x 5 year olds!!!)
It was great fun... the kids loved it... and the adults had to hold themselves back from helping too much!
