We recently shared a way of using excess mash for breakfast by turning it into delicious potato pancakes. But how about using mash in a dessert? Discover how to make mashed potato sponge cake!
I could wax lyrical about potatoes for hours. In fact, I probably already have. My name is Victoria and I am a potato addict. Roasties, chips and mash and that’s before we’ve even approached gratins, pommes soufflés and röstis. There’s no doubt that this humble tuber is seriously versatile. If, like me, you are a total spud head and proud, you will no doubt occasionally be guilty of overkill. Especially when it comes to mashed potato. It's just too easy to carry on peeling and peeling.

, poached some berries in a pipe tobacco and star anise syrup and balanced it all on a rectangle of Maris Piper potato sponge cake. It was light and fragrant and, despite the fears of some that the tobacco syrup would make the whole dish taste like an overused ashtray, it received unanimous thumbs up from all. It really is a great way to use up your mash.
