Some combo of all three? Something else entirely?
I ask because I generally do not eat button mushrooms (fresh, or canned), and can't really recall what they *should* taste like. (FWIW, I eat and enjoy just about all other 'shrooms.)
But today I had some fresh button mushrooms that tasted like diluted licorice with hints of iodine solution.
Yuck. Just yuck.
So, what should fresh button mushrooms taste like?
