My friend is coming round for afternoon tea but she has recently gone gluten free. I can’t go to any of my go to recipes and I don’t have any gluten free flour in the cupboard. I have a scroll through some websites and come across a nice looking gluten free lemon drizzle cake. Scanning my eyes down the list of ingredients one thing jumps out at me – mashed potato! Mashed potato – in a cake – is this a thing?! When did this become a thing? Potato cakes as a savoury item, sure, but in a sweet cake? Well, always (or perhaps just sometimes) one for adventure I decide to give it a go.
