Is dark chocolate good for you? Could daffodils help treat Alzheimer's disease? Jimmy, Kate and Matt uncover remarkable secrets about the nation's favourite springtime produce. Chocoholic Kate heads on a pilgrimage to a cocoa farm in Ghana to find out if there's any scientific truth behind the widespread belief that chemicals in dark chocolate have health benefits. Jimmy investigates why rabbit is stocked in supermarkets on the continent, but not in the UK. Does our association with pet bunnies dampen demand from British shoppers? He gets rare access to a rabbit farm in Spain to learn more about the industry. Matt goes on a real-life egg hunt to find out more about double yolks. But with 1.5 million hens eggs laid every day at just one UK farm, he may need to use some special techniques to find the rare 'double-yolkers'. Jimmy also heads to Hampshire and discovers that the tender spring lamb served at Easter may be older than you think.
