Canned tuna. Childhood daycare food. Both my brother and I can’t stand it. It never made me vomit but it was a real challenge to get down, and I think he threw up from it once. I’m not sure what she did to make it so vile but there was a lot of mayo too and I couldn’t handle mayo for a very long time.
Honestly, it has never occurred to me to try any canned fish. I don’t even like seared ahi. As soon as it’s cooked at all, it tastes like the nasty childhood tuna. Fully raw sushi tuna is okay though, thankfully.
