Harker told WBZ NewsRadio's Kim Tunnicliffe he and his partners at Eastern Standard Provisions were thrilled when they got the news.
"We just looked at each other like, is this really happening?" he said. "We knew we had a great product, but just never imagined it would get that kind of attention ... Oprah actually tried the pretzels."
Once Oprah's "Favorite Things 2019" list aired on Good Morning America, Harker said, sales skyrocketed.
"If we were maybe doing 1,000 orders a month before Oprah, we did about 15,000 boxes of pretzels in just that couple weeks since the announcement," he said.
Thankfully, Oprah's representatives gave the company a heads-up that the pretzels would be on the list. Harker said they had to gear up for the big boost in business.
"We hired extra people," he said. "We had to make sure the website was able to handle volume."
Now, a banner on their site reads, "OPRAH'S FAVORITE PRETZEL—It's official and we couldn't be more excited."
Eastern Standard Provisions is now hoping to take their brand national.
