I put it down to the usual practice of someone liking something, making it, tweaking it, but keeping the name, or substituting in a different ingredient, but keeping the name.
Maybe but we are talking Julia Child and Jaques Pépin here. I wouldn't expect either to do that. Or at least if they did I'd expect them to explain.


First you don't grill under a grill, but on top of a grill. Now you grill things, but in a skillet, without using, er, a grill at all.
