Paul goes in search of some of Japan's strangest food stories on the final leg of his journey. He competes in a noodle eating challenge against two internet celebrities, who have acquired a cult following for their ability to consume vast amounts of food. He also pays a visit to a sumo wrestling stable, where he bakes flatbreads for the fighters and sits down to dinner with the largest fighter in the history of the sport. He then takes a trip into the countryside to visit a farm for very expensive strawberries, and concludes the trip with Osaka's eat-till-you-drop food tour.

Paul Hollywood goes on a culinary voyage of discovery, beginning in Mexico City, where he discovers the dangers of avocados and learns how to make Pan Dulce - Mexico's favourite bread. He also attempts to eat a tarantula, goes on a takeaway food tour of the capital with a biker gang, and plays the ancient Mexican game of Fire Hockey.

Paul attends a quinceañera in Baja California, visits one of Mexico's best restaurants on the Yucatan Peninsula, and judges a pasty baking competition in a town with a surprising Cornish heritage. Along the way, he samples some unusual Mexican staples - fresh cactus in Milpa Alta and insects in Oaxaca.
