Back in the day (early 90s) my mom would sometimes serve Karo corn syrup on pancakes, even when we had maple syrup around. I thought it was a typical thing for a long time!
You'd have a lot of recipies call for some amount of corn syrup but rarely go through a whole bottle. Mom probably didn't want to just throw it out, and the Aunt Jemima was pretty much the same with some caramel color and a few other added flavors. Might as well use up the two year old Karo on the kids waffles and get some fresh stuff for the next holiday baking season.
