It's the semi-finals, and the remaining teams must draw inspiration from the office of headmaster Albus Dumbledore's office, which houses many iconic items from Harry Potter lore. And since the office is also home to Fawkes the Phoenix, hosts James and Oliver Phelps request that part of each team's 4-foot-tall showpiece should appear to be transforming from one thing to another. Plus, the tasting elements must highlight two of the four pillars of flavor: sweet, sour, spicy and salty. Harry Potter alumna Bonnie Wright joins judges Carla Hall and Jozef Youssef to decide which teams will go on to the final showdown.
