Jimmy and Jamie want to see if British puds can beat Italian desserts. Jonathan Ross pops into the caff to cook extra-special bread and butter pudding with the boys and to take on the 'After Eight challenge'. And Jimmy investigates whether science can help to fight our ever-growing portion sizes. The Italians are mad about desserts, and from tiramisu and panna cotta to ice cream they've turned the humble pud into an art form. The boys go head to head with a major Italian pastry chef at a lavish Italian wedding banquet. And after the dust settles it's time for Jonathan to join Jimmy and Jamie for a burger and fries on Southend's rollercoaster.
