I think pullas should not be considered as a typo. I'm not sure how to report this. I chose Something else went wrong option.
Having lived in Finland for a while now and having eaten many pulla, "pullas" just sounds wrong as a plural in English.
pullat are buns (verified by a native Finn)
No, they're not. There is no translation. You can read more for example from the numerous different discussions about this in the forums here.
So, are you saying that a born and raised Finn doesn't know her own language? Cute...
