Not American but Gnotschi

G as in GIF

I am a heathen, so usually NO-Key, but in culinary circles people who want to nod in the general direction of proper Italian will say something closer to knee-YO-key. Mid-word vowel sounds in American English (all English?) can be extremely variable, though

If you want a proper IPA transcription, this video seems about right.

nyochi (where the ch is more glottal than tch-y)

Any hope for it being anything close to the original is a lost cause at this point.

Just like everything else they do!

Lollllllll

Yokey with the subtlest little ng at the beginning.
