Goldenberg's Peanut Chews were born out of necessity in the trenches, fueling soldiers on the front lines. Today, they thrive in snack aisles, still made right here in Philadelphia.
"It's that nice combination of crunchy peanuts, chewy, gooey molasses center covered with that really good dark chocolate," said Keith Domalewski, director of marketing.
But the bite-sized confection wasn't always enjoyed as a treat.
"In 1917, it was developed as a high-protein, high-energy ration that the troops just fell in love with," Domalewski said.
In many ways, it was the original energy bar - introduced by the Goldenberg family, who operated a store on Frankford Avenue.
"And so once the war was over, there was a ready market for folks to enjoy that brand here, not as a ration but as a treat," Domalewski added.
In 2003, the brand was acquired by Just Born, the Bethlehem-based candy maker known for Peeps.
The original Goldenberg recipe is still used today, now available in two flavors: original dark and milk chocolatey.
"We go through about 40,000 pounds of peanuts here every week, week and a half," Domalewski said.
More than a century later, the Philadelphia factory produces 1.2 million Peanut Chews every day.
