Oh yeah, I know exactly what you're talking about. It looks like a perfect strawberry, no blemish, no nothing, it may even smell a little like strawberry, right? But - it is now weird, alien abomination that made its way into your fridge. Beware, GalenKP! These imposters are vicious or maybe they're just bad not tasting at all.
I have avoided buying strawberries for years because of the very same experience. This year was the first that in the height of strawberry season we got some that were actually really good.
I hope you'll find good strawberries next time. Don't give up on them. They're yummie!
