Thanks for this ping! A couple of years ago, I sawed off the bottoms of a couple of tuna cans to make molds for a quick bread recipe you posted (it had a touch of yeast—you said your baker grandpa didn’t even make his own—was it crumpets?) and I almost amputated a digit making the molds. Discretion being the better part of valor, I backed away from your recipe. They started letting me have sharp objects again this year. :)
It was indeed the infamous Crumpet.
Considered to be far to complicated for a mere mortal to create....
