Looks like there was a Fox viewer mentioned in the article who thought the same

A user wrote, “When I first saw this clip, I thought she meant that Charlie Kirk has a favorite type of hot sauce and when she sees it, it reminds her of him. But no, Charlie Kirk actually owned a hot sauce brand that Erika makes money from.”

I love hot sauce myself and I’ve even made some stuff with hot peppers I’ve grown, but when it comes from a right wing douchebag I can’t help but think he was just doing it for his brand. Guns! Hot sauce! Xtreminate your life with KIRK SAUCE!
