If he can get the proper ingredients. Good luck trying to get a roll like Amoroso's over there.
He's got France and Italy right there, I'm sure he can find some good rolls. Where do you think the Amoroso family came from?
"Right there." You can't get Amoroso's more than 30 miles outside of Philly, and you're expecting him to go 500km to Italy for rolls? Then don't forget Brexit; it's not gonna be easy to import even if he were willing to.
There are Italian people who moved to the UK and opened bakeries, especially in London.
