Peanut butter and jelly. Bacon and eggs. A burger and fries. Some foods (and flavors) are meant for each other. But which flavor of potato chip goes best with a Philly cheesesteak, or a BLT or a meatball sub?

To settle that lunch dilemma, Herr’s and its flavor development team have created potato chip pairing guidelines for a variety of sandwiches — and, yes, there’s actual flavor science and expertise behind the recommendations.

“You’ve got a sandwich, and you’re staring at a rack of chip flavors, but which one do you choose?” said Pete Graziano, Herr’s Research & Development manager and corporate chef.

“It’s a challenge everyone has experienced at some point, and it’s not always an easy decision.”

Some pairings are all about contrast, while others are more complementary.

“In the end, just like wine-and-food pairings, it’s really all about your personal preference,” said Graziano. “But the right combination, with similar tastes and perfectly balanced flavor profiles, can make the difference between a good lunch and a great one.”

Here are Graziano’s recommendations:
