Gooey butter cake started out as a baker's mistake, but turned into a St. Louis specialty adored by one and all. Iron Chef Michael Symon heads to the Gateway City to get his fingers sticky and settle a feud between Park Ave. Coffee and Gooey Louie's, two places that use old family recipes to make that famous confection. Helping Michael along the way are pastry instructors from the L'Ecole Culinaire school, Missouri natives and lovers of all things goo. In Cincinnati, the ice cream may be cold, but this rivalry is steaming hot! Graeter's and Aglamesis have been churning out chocolate chip ice cream the old-fashioned way for over 100 years, and the good people of Ohio are divided. Take a step back in time as Michael Symon learns the techniques that give each hand dipped scoop that unmistakable flavor and he crowns a champion of the chip!
