French fries cut no thicker than 0.28 inches. No more than six patties on a grill at a time. These were just a few of the contributions to the McDonald’s operating “bible” from Fred Turner, a former long-time employee. Now 70, he is back on the job, brought in by exec Jim Cantalupo who himself came out of retirement to shine up the golden arches. Turner is in charge of product improvement, meaning he’s working on ways to make their products more appealing, and also trying out new items. Perhaps he will bring back Julia Child’s favorite beef tallow fried french fries.
