I was given Sue Shepherd’s recipe book, ‘The Gluten-free Kitchen’ for Christmas and have already made two cakes out of it. The book has wonderful photos and easy recipes that don’t involve too many ingredients.

For my Mum’s birthday I decided to make the Banana Hazelnut Cake. I was intrigued to see that the recipe included 150g mashed potato (instead of flour), however the forward of the recipe actually notes not to be alarmed about this unexpected ingredient.

The cake turned out amazing and everyone highly enjoyed it – some even going back for seconds – and you wouldn’t even realise that it had potato in it!
