McDonald's US has imported a popular concept from its franchise cousins in Asia that will allow customers to punch up their fries with different seasonings.
After debuting in Hong Kong in 2005, the first Shakin' Flavor Fries has hit restaurants in Northern California, where customers can season their fries with flavors like garlic parmesan, spicy buffalo or zesty ranch.
Much like the US chicken seasoning concept Shake 'n Bake, which comes with a bag and seasoning spices, Shakin' Flavor Fries also comes with an additional 'Fry Bag' and seasoning packet. Customers are to throw the fries and spices in the bag, and shake.
Known as Shake Shake in Asia, the menu item has been available for years in China, India and Australia.
The product is being launched locally, but could expand nationally.
It's the latest move out of the fast food burger industry to pump up the standard burger accompaniment.
Last fall, Burger King reduced the calorie and fat content to launch its new Satisfries, while Wendy's revamped its spuds, pitching them as 'naturally-cut" fries cooked with the skin on, and sprinkled with sea salt.
