I’ll read how a cooking oil will become rancid, or the oil in nuts, or the oil in whole-wheat flour. But I never notice. I never find that something has now become disgusting in that way.
(Although I’m not crazy about nuts to begin with, and I’ve never had a fresh one from a tree or anything, so it’s possible I’m reacting to something there.)
How much do you notice rancidity? Do the people around you detect it similarly?
Some discussions online mention rancidity in connection with supertasting, but I strongly suspect I am a supertaster because I have to go very light on most bitter ingredients, cut back on sugar in a recipe so it doesn’t just taste like sugar, find too much fat to be gross, and so on. [Reading about supertasting is such a blend of sadness and vindication. You mean grapefruits are genuinely supposed to taste good? And an avocado all by itself? And raw pineapple? Honestly?]
I understand what you are saying, I don’t know that I taste it, even in the same batch that others do. My thoughts are it comes to experience. I don’t use olive oil, or butter, alone, just in cooking, but if I sample it, it always tastes fine. But with tea, then ya, it was too hot water, or over steeped. But I do drink a lot of tea. Maybe we both could benefit by going to some tastings. And bring some rancid oil with us to compare? Not sure how popular we would be ☠️
