While the fresh patties will cook faster than frozen ones, the transition will be a costly one for McDonald’s, requiring changes in storage and shipping. CNBC says “McDonald’s suppliers spent upwards of $60 million updating their supply chain to transition from frozen Quarter Pounder patties to fresh ones”—clearly, a gamble that McDonald’s thinks will pay off. But tinkering with such a tried-and-true, decades-long classic like the Quarter Pounder certainly will not be without its risks—not unlike messing with the beloved Coke formula, and look how that turned out.


Still, CNBC notes that “After the test of fresh beef in more than 400 restaurants in Texas and Oklahoma, the company said it received a 90 percent satisfaction rating from customers as well as a 90 percent intent to repurchase rate.” No word yet on the transitional fresh/frozen status of McDonald’s non-quarter-pound patties—for Big Macs and traditional cheeseburgers.
