Whether or not you have fond memories of licking red-stained fingers as a kid, many consider ketchup chips to be a Canadian classic. But why is the flavour so popular here compared to the rest of the world? We ask Janis Thiessen, history professor and author of Snacks: A Canadian Food History, about where the potato chip comes from. Then, we chat with Kathlyne Ross, VP of Food Product Development & Innovation for President’s Choice, about how well the flavour sells in Loblaw stores across the country—including which province is home to the most ketchup-chip fans. Finally, we hear from international snack expert Monique Bernstein, who tells us the one other country where you can find ketchup chips readily available—and names some of the other interesting chip flavours out there.
