There are many cities that claim to be the home of the hot fudge sundae, but they’ve all got one thing in common: they’re American cities. Hot fudge sundaes are about as nostalgia-tinged as it gets: they’ve dotted pop culture for decades, further back than their cameo in Full House’s “Gotta Dance” episode, and more recently than in Katy Perry’s “California Gurls” video. Hot fudge sundaes have dominated the ice cream landscape for decades now, and on July 25, we celebrate: raise your spoons for National Hot Fudge Sundae Day!
