Thanks to Instagram and the Great British Baking Show, home bakers have significantly upped their game. Here's how to use ...

If you would like to cover the cake with ready-to-roll fondant icing, dust a work surface with cornflour. Knead a dash of food colouring, if using, into the fondant until evenly coloured.

Roll the light blue fondant out onto a surface dusted with cornflour, to around 5mm thick, or until you have a sheet big enough to cover the cake. Trim off any excess using a sharp knife.
