Maybe it was a recipe printing error, your preparation mistake, or just a downright disgusting combination that didn't seem so until you made it. Tell me!
I ask because last night, in an attempt to try a new, quick recipe, I made something even my most open-minded taste-tester refused after a bite. It was a simple sauteeing of red cabbage and onions with some balsamic vinegar, s&p, and corn. It was gross! And smelled bad! I needed white vinegar just to get the smell out of the pan. Never again.
