This is one of those "Now why didn't I think of that?" things. I love roast
chicken but the Julia Child method of hovering over the bird like some
guardian angel never appealed to me.

Butterflying turns the bird into a more or less two-dimensional mass whose
cooking is easy to manage. This method didn't exist 50-30 years ago so far
as I can tell.

Who invented it and when in the last two decades?
