Of course!
I just remembered an amusing plot line from an otherwise so-so “fish out of water” sitcom called “Bless this Mess” involving this particular appetizer. This is all from memory, so I won’t get the details exactly right:
Dax Shepard and Lake Bell play a NYC couple who move to a small town in the Midwest. A town pot luck is coming up, and, eager to fit in, the Dax character asks his neighbor who is organizing the pot luck if he could be assigned a sure-fire hit for a dish to bring.
She tells him “here’s one you can’t screw up and is sure to please: put equal parts grape jelly and Heinz chili sauce into a crock pot. Don’t mix. Add meatballs.”
On pot luck day he’s excited for her to try his meatball dish. She does, and immediately yells out angrily “YOU MIXED IT!!!”
