McDonald’s announces ‘Grandma McFlurry’: But what’s in it?

McDonald's has introduced a new "Grandma McFlurry," available from May 21 for a limited time. This dessert features vanilla soft serve mixed with a mysterious "delicious syrup" and candy pieces, inspired by nostalgic treats reminiscent of those grandmas might carry in their purses. The exact flavors remain undisclosed, with speculation around butterscotch components. McDonald's will promote the new McFlurry with a special mobile event in New York City, offering free samples before its official launch.
