A popular children's sandwich in NorthEast US is a PBM a peanut butter and marshmallow fluff sandwich using white bread.
It morphs into a comfort food for adults who grew up with PBMs.
It's generally pronounced "Marshmelo" accent on Marsh and the rest kinda swallowed.
When I lived on West Coast of US for awhile I could not find Marshmallow Fluff in any store ... they had a kind of runny marshmallow creme -- yuk -- too oozy for a sandwich but ok on ice cream sundae.
Neither is Fluff available in Hawaii. My son lives and works in Hawaii and I have to send a box of Fluff to him periodically. He keeps bread, a jar of PB and a container of Fluff at his office for mid-afternoon pick-me-ups.
(At 6"2" and carrying 175 lbs of muscle he can afford the indulgence!)
Any New Englander who catches him preparing his snack yells "FLUFF ! Where did you get it?" and he shares -- in the fellowship of all displaced Yankee.
Are you carrying "Fluff" to the UK ? Or just the little pop-in-you-mouth balls of picnic style marsmallows?
wow
