A  Cutthroat Kitchen judge since the earliest days of the series, Antonia Lofaso surely knows the ins and outs of the competition. But on tonight's all-new episode, she proved just how much of an expert she is in the world of master sabotage. "Round 3: blondies. And our very first one was this interesting brownie pan," Alton Brown said to her during the host's After-Show while introducing her to the pan. He was about to explain the intricacies of the sabotage but didn't manage to finish his thought — "Whoever got stuck with this had to do all of their mixing" — as Antonia simply cut him off, knowing exactly what he was about to say. "Mixing and prepping inside of the container!" she said, much to Alton's chagrin. "You mock me!" he joked with her.

She was somewhat certain that "we always do this for cakes," and indeed similar vessels have made appearances for past baking rounds. But Alton noted: "We don't need new ideas when the ideas we have work. Maybe we just need judges that aren't so pointing out of that." They laughed about their exchange, and sure enough, Antonia was able to discern which of the two remaining chefs received this challenge for his blondies.
