The gluten-free, milk-free, wheat-free Gingerbread House Kit from Tesco (£4) requires bakers to build their masterpiece from gingerbread mix. This is a great way to introduce little people to baking, as they must learn to weigh ingredients, knead mixture, roll dough and cut shapes, with guidance from someone experienced, of course. Then it’s time for the fun part – decorating with icing and jelly beans.
