They really do need to have food add more actual gameplay like this, I honestly don't care that we have 234905390349056 things to prepare in Sims 4. If anything, it just clogs up the menu. I was fine with the few choices we had in Sims 2.
Some slight negative moodlet just won't cut it.
With spicy food I'd love to see sims sweat or maybe have flames come out of their mouth when they can't handle it, rushing to drink something. Could be trait related, some traits causing them to handle it poorly while others like hothead could be able to handle it perfectly fine. Could be a fun little positive side effect of the hothead trait.
Some types of food when poorly prepared, like tacos perhaps, could also cause sims to sit on the toilet a longer time after eating it, maybe even running to the toilet if it's really bad. Sims need to run to the toilet when they truly have to go either way, I hate that stupid slow constipated walked they do in sims 4. That should be exclusive to proper sims, they are the ones with a stick up their butt after all.
Problem with the puffer fish is also that it's merely a chance of death. And anything in sims 4 with a chance of death seems to have a very low chance at that. So that chance should be increased for certain, like only if perfectly made would it be safe, and anything less could be deadly.
And a few other select meals could only be deadly if spoiled or of poor quality, unless it's a slob who eats them.
I personally would not mind some option to actually poison food though, and allow for indirect murder that way.
