Bacon
(It really doesn't agree with me if it's crispy. And limp bacon is impossible to get at a diner.)
I can not really eat bacon if it is not really brown and crispy.
To me a restaurant can not cook bacon fully, to my satisfaction. We could probably never live together.
That brings back memories.
A student house I lived in, and one of the ladies really could not cook. Whenever she would make something with bacon, the other students were glad if I was in early. Because vegetarian or not, the sight of badly treated bacon is a pain in the eye. I would take all the time to give it slow love, getting it very crispy. I was the bacon expert.
Worst thing the housemate could cook was red cabbage though. It would end up like light green goo, without any taste.
Every monday, when this girl had to cook, one of us would try to be home early, to assist her, and hopefully teach her something.
