just going back to “pie” being a new haven ct thing. i have idea where you’re from. but pie was always pizza and you put gravy or sauce on fries
Live in Connecticut, but I'm from Massachusetts, and my parents (Mom is 100% Italian) are from a predominantly Italian neighborhood in the Capital Region of NY.
First time I recall hearing pizza referred to as "Pie" outside of the song, was in Storrs, not New Haven.
Still don't know what you are getting at re: gravy. There is a diner on Route 9 in Westborough MA that serves an app of fries and brown gravy. I don't typically put tomato sauce on fries.
Ketchup is pretty much a last resort. Whatever you put ketchup on as a 10 year old, BBQ makes it 20x better.
