It's time for some sweet summer treats! First, Antonia Lofaso challenges chef-mentors Tiffani Faison and Brooke Williamson to team up with a chef of their choosing to make their best hot and cold duo. Then, the chefs participate in a boardwalk bake sale, feeding not only the judges but also some lucky folks on the pier. In the end, guest judge Stephanie Boswell helps send one chef home with a salty taste in their mouth.
