The Kitchen is savoring one last bite of the flavors of the summer, starting with Katie Lee's French Onion Burger and Jeff Mauro's Whole BBQ'd Cauliflower. Food writer Alison Roman bakes Pistachio-Plum Crisp, and then Katie throws an Ice Cream Party. Geoffrey Zakarian and Sunny Anderson team up for a hot dog duo with his Spiralized Pineapple Relish Hot Dog and her Jalapeno Popper Dog. Finally, summer finishes off with Geoffrey's Bacon Wrapped Pineapple and Sparkling Pineapple Punch.
