I’m a super taster as well. Raw onion is a hard no for me, but caramelized onions are like a cheat code for making every meal delicious.
But you’ve got the artificial sweetener thing backwards. Super tasters tend to prefer real sugar and find the fake stuff cloying and unpleasant. I’d bite into an onion like it was an apple before I’d drink a diet soda.
Also, mayo is delicious.






My son pretty much eats his hot dogs this way. He eats a lot of foods this way. When he eats half a donut, it’s usually the top half.
