Ah, I should have thought before I typed - It's a regional thing.
Marshmallow Fluff is is a New England thing and is a goopy cream the consistency of mousse and made from Marshmallows. Wicked good stuff but only found here. When I was overseas in the late '60's my Mom would send several big jars of it once a quarter. Mix it with peanut butter on a sandwich - pure heaven.
That goes along with Autocrat Coffee Syrup which, as far as I know, is only found in Southern New England and is used to make Rhode Island's official drink, coffee milk.

Ah, Rhode Island, the only place I know of where you can buy a coffee milk shake, but it's called a "Cabinet".
Wicked Fresh seafood there, too:
Clams are bigger in Rhode Island - That's why they're called "Stuffies"......Well, the really big ones are called Quahogs, actually (pronounced Koe-Hog, not cwah-hog).
I'll be riding my bike into Rhode Island a little later today, making a loop down to Woonsocket and back. BIG old now-defunct textile town full of French Canadian descendants with the best Jazz club in New England (CHan's) - Go figure
