This month’s Cookalong is Nigella’s Edible Christmas Tree Decorations, a peppery and gingerbread-spiced dough that’s rolled and cut into Christmas shapes, before being iced and then hung on your tree. The cookie cutters you use are up to you, just remember to make a small hole so that they can be hung with ribbon or wire later. Instant royal icing is used to decorate as it gives a thick icing that sets hard, and the choice of sprinkles and edible glitter is up to you. So get festively crafty, and then photograph your Edible Christmas Tree Decorations, add your caption, then send it to us, and you will then be in the running to win a signed book of Nigella’s. We will upload your entry, and will announce the winner in the new year.
