I’m at Smize and Dream, the ice-cream shop founded by supermodel, Harvard alumna and entrepreneur Tyra Banks. There is a steady stream of customers for a weekday afternoon in Sydney’s Darling Harbour. I’m here for the Hot Mama, which Banks debuted in September, and claims is the world’s first hot ice-cream.

According to its creator, the new dessert is neither a latte nor a hot chocolate and certainly not melted ice-cream. But if it’s none of these, then what is it?

“Liquid, warm, soothing, yummy, silky,” Banks wrote on Smize and Dream’s Instagram. Its enigmatic description has seen people sharing their hottest takes on social media, with some video views in the hundreds of thousands.
