I was watching some Youtube channel, maybe 'Alex French Guy Cooking' and, while I suspect there was some pre-planning, he seemed to be bemused by the the fact an omelet was what someone wanted him to do. Of all the things he's created in his life. People keep wanting him do an omelet.
Well, he says that his test for a new cook is to make an omelet.
And that's really it, isn't it? I think that everyone wants to pass that test.
