Yeah mushrooms contain a good amount of umami (one of the ingredients of meat that makes it “tasty”). For me it took quite some time (maybe 2-4 years) until my gut adjusted to the taste of a (mostly) vegan diet. But then there’s just a lot more diversity and interesting taste otherwise. With a good amount of experimentation combining all kinds of different things to compose a unique taste. With meat it’s often just the main taste-defining/dominating ingredient (so kinda boring?). I avoid the highly processed “meat”-replacements though, maybe that helped a bit to get my taste away of meat.
It has, as voter turnout could be significantly better. It’s not yet clear what it is, but so far it doesn’t look very good.
