Is this a food rant? Maybe not. It's a food-related rant though: a griddle is flat. A flat surface. Not a ridged surface to make it look like food has been char-grilled, but a flat surface. Want to try cooking griddle cakes on a ridged surface?
No? Me neither.
A modern, ridged, existed-for-less-time-than-people-have-been-saying-the-word-"griddle" pan is not a griddle. It's a ridged pan. Or a chargrill-pan. Or something else that isn't a griddle. It's a new thing, so coin a new term rather than pinching one that's already busy meaning something else.
Why does this matter? Language evolves, of course, and words take on different meanings. I'm perfectly well aware of that. I'm not a language snob who takes superior delight in saying "Can you? I don't know if you can, but you certainly may..."
The reason it matters is because a griddle - an actual, real, what-a-griddle-has-always-been griddle - is still a chuffing griddle, and if you're trying to shop for one, it's really bloody tiresome to find thousands of listings for the WRONG BLOODY THING.
