As a young man, Jay Allen worked on an ice cream truck.
Now he owns an ice cream shop called Jamz Creamery."We've got a signature item we call the Jazz," Allen said.
"It's an ice cream and cake sandwich.
It's kind of build your own.
You choose the cake, you choose the ice cream, you choose the topping." Along with their signature Jazz ice cream sandwich, the Inglewood, CA shop is also known for its jams.
