Midterm exam time. Who sailed, who failed? And what made Paula Deen bring up her string bikini and the quality of her grandchild's cooking ability? Who came out on top--Team Serena or Team Brianna? Did Herb get back on track or crash and burn? Oh the suspense! There was too much drama to fit into an hour this week, so we got extra time and a bonus live chat with season four finalist and Food Network star and funnyman Adam Gertler. Like a Kid in a Candy Store--that's his sweet new show--Gertler zinged fans with running commentary and an admiration for all things Serena. Even Mr. Flay joined the fray with live tweets. The finalists faced two challenges: First, create "you in a jar" and present it to a big-ole live audience. Then they had to team up and run a food truck. That's when the twists and turns arrived. Some happy surprises--two chicks seemed to reach detente ("The empanada, y'all, is really good," Paula said), for now, which bizarrely disappointed chatting fans. Check out the chat below for details, then jump behind the scenes for Bobby's recipe makeover of finalists' dishes (would love his pointers!) and vlogs from Bob, Susie and Giada. Then vote for your favorite finalist, up to ten times per day. Meantime, I'll be wondering if Brad should let dark horse Tom borrow his lucky hat, and if Adam might borrow one of Bobby's ties. A+ episode, everyone.
