Meet Grantham's gingerbread man! Baker Alastair Hawken teaches Natasha Raskin Sharp about the resurgence of Grantham gingerbread, after it was invented by accident over 280 years ago. Can the teams make some dough of their own as they shop at Newark antiques fair before selling their items at Colin Young's auction? Hoping their profits will rise are father and daughter doctors Kash and Ayesha on the blues team. And in red, hoping to prove themselves worthy of a golden gavel are sisters Ellie and Alicia. With expert Mark Stacey by their side, Ellie is in a spin over a child's spinning top, but Alicia is not convinced. Meanwhile, the blues spot a pricey ceramic elephant-shaped planter, but Catherine says not on your Nellie! Keep watching until the end of the show for a particularly heartwarming win.
