Am I cooking mushrooms wrong? Since I was a child, I never really liked mushrooms. To be honest, I was extremely picky, but now, I eat anything. Well... Almost anything. I can't stand mushrooms. Except, I can't understand why, and I want to learn to love mushrooms since they're really useful as a vegetarian.

For example, yesterday, I made some pretty simple miso soup and added some, supposedly delicious shiitake mushrooms to it. I salted them and fried them at medium-high heat for a few minutes until they had a nice color and texture. Did doing that affected the taste in a bad way?

I also remember making mushrooms risotto some time ago and getting the same disgusting taste.

Am I missing something obvious here? Is this not how you're supposed to cook mushrooms?
There's nothing wrong with the way you cooked those mushrooms, you fried them to give them some color and seasoned them, which is perfectly fine. You didn't mess them up, you just don't like them. No matter how you prepare them you probably still won't like the flavor, there's nothing wrong with that, it's just how you are.
