I had to break my doughnut hiatus for this. This sea salt caramel and banana doughnut (£3.50) from Crosstown Doughnuts might cost quite a bomb for a small ball of deep fried dough, but it's packed full of flavour with yummy banana cream filling, drizzled with sea salt caramel and sprinkled with chocolate soil topping. Be prepared to get your hands and mouth dirty - that's the only way to enjoy this.
