When I first saw the title, I thought this was a quiz about associations for different produce. For example, pumpkins might be the Official Pumpkin Protection Committee (OPPC).
Personally, I've never heard of sweet potato pie. We always eat pumpkin pie on Thanksgiving. According to Wikipedia, it's mostly a southern dish https://en.wikipedia.org/wiki/Sweet_potato_pie
For smelly you could include cauliflowers and brussel sprouts. I think they are much more widely associated with smelliness than the rather obscure (for a large part of the world) durian.
