My grandmother cooked beans in a pot that stayed on the back ring most of the winter. When she died nobody could reproduce it, including three people who had watched her do it.
What everyone got wrong
We all assumed it was a long list. It is four things and a lot of time. The mistake was salting at the start, which every one of us did, because that is what you are taught.
The phone call
My aunt, who does not enjoy being asked about the past, told me two things in about nine seconds: the butter went black, and the pepper went in when the pot came off the heat. Attempt eleven worked.
The card is short. Most of the good ones are.
