And now there are 6 chefs remaining.  In this "all-American" episode, the Chairman's charge is RESPECT.  Today's secret ingredient challenge is to show respect for the potato (the peeling of which was formerly military punishment) by creating a potato dish in 45 minutes. In the Chairman's Challenge, the chefs are asked to show respect for America by cooking 4 dishes that represent the 4 main regions on the map of the US – north, south, east and west.  

Stress levels skyrocket as the remaining chefs face the test of seduction. In the Secret Ingredient Challenge, the competitors find themselves at the bar inside Jean-Georges Steakhouse at the Aria Hotel, where they have 30 minutes to create a cocktail and snack using liquor that seduces the judges' taste buds, including guest judge and renowned mixologist Charlotte Voisey. Next, the chefs meet host Alton Brown in a posh Sky Villa on Aria Hotel's 59th floor for the Chairman's Challenge. They have only 90 minutes to create an elaborate three-dish meal using luxurious ingredients gathered from restaurants in the hotel. Two chefs leave in an intense double elimination, and the last two standing prepare for the final battle in Kitchen Stadium.
