The RATIONAL Solution.

RATIONAL was the first combi oven Chef Keller used in the 90s, and it has featured prominently in his kitchens ever since. Combi technology and the dynamic cooking range it provides has been instrumental in his cooking techniques.

“The RATIONAL SelfCookingCenter® has given us the ability to be dynamic with our dishes and develop a menu that is continually evolving,” Chef Keller said.

RATIONAL ovens play a role at Chef Keller’s restaurants and bakeries. The prep and pastry kitchens use them throughout the day, while chefs also rely on them for à la minute preparation. The French Laundry kitchen recently underwent a complete renovation, and RATIONAL remains a cornerstone. “RATIONAL is a part of our brigade on the line.”
