Using blurs and slurs and words that don't fit

Gael Greene goes on beyond the OED in recalling her best meal evs:*

 Choose the best meal I’ve eaten as a restaurant critic? My brain reels in a barrage of taste memories; it’s all but impossible to single out just one. But for an all-time cuisinary high, that first astonishing dinner at the preposterous Palace stands out from the 18,814 meals I’ve eaten as a restaurant critic.

Cuisinary? Nice to meet you. Nothing wrong with inventing words when there is not one that will do. Justsk Uncle Grambo, or Shakespeare. But when a perfectly cromulent word like "culinary" exists, is it worth effing with "cusinary"? Don't print publications have editors to keep an eye on this kind of thing?

*If you were hoping that the answer would be "Sonic drive-in+ romp w/ Burt Reynolds in the back of his Impala, ca. 1978," you are far from alone.
