This bit, I'm really unclear on as if the CORS was wrong for the entire api endpoint; I wouldn't have expected recipe CRUD to have worked.

See vaguely similar to #4902
nuxt/nuxt#15332 possibly resolves it but is messy for a first run dev experience.

Edit:
Okay, normal API calls are fine due to the CORS header sent on the GET of the page.

But that doesn't whitelist the ingredient endpoint for some reason.

And annoyingly: crf++ not availableas a python package or easily installable.
