BENSENVILLE, Ill. -- Despite all the talk of economic woes, there's at least one Chicago business that's going strong.

It's a factory that's so busy, it's created more than 80 new jobs in the last four years.

NBC5's Rob Elgas said Thursday that the factory is in suburban Bensenville and, for the first time, TV cameras were allowed inside for the report he prepared.

With the "Marshmallow Mystery Tour," Elgas took viewers behind the scenes at Doumack, Inc., where it's not Oompa Loompas whipping up the sweets, but rather an around-the-clock operation of workers who take pride in their jobs and their product.

They make Campfire Marshmallows for distribution to more than 50 countries around the world.

Mark Schuessler, vice president of Doumack, said that the production of marshmallows has become part of American lore and history following the popularity of the film "Willie Wonka & The Chocolate Factory," but for him, it's always been a great place to work and a fun product to be part of.

"We do take our jobs seriously," he said. "But, we have a blast."

The company has been making the circular 1.8-inch logs of white, sticky, fluffy, gooey marshmallows for nearly a half-century, Elgas said.

President Barry Blum showed Elgas the line operation. He said the recipe for marshmallows calls for corn syrup, sugar, water, dextrose and -- "the magic ingredient" -- air.

Doumak delivers its delectable delight across the world, using roughly the same method that's been used since the marshmallow arrived in the United States in the early 1900s.
