This morning on NHK Japanese National TV there was a short feature on an Australian person who is running an English school, teaching language and cooking at the same time.
As a part of the scenario reporter was preparing an egg with spinach on a fry pan. At one moment the Australian teacher instructed him to put "pienuts" ([paɪnʌts]) into the frying pan.
The reporter seemed also confused and the word was repeated by both of them three times altogether. There was no chance of mispronouncing or mishearing. The dish could not be called a "pie" in any way either. The ingredient was a bowl of nuts of some kind.
Is it a regular pronunciation for "peanut" in Australian English or anywhere?
