Dutch mayonnaise is in one of the dialogues of Pulp Fiction (1994). In the scene Vincent (left) and Jules (right) drive in their car and have the following dialogue:
“Vincent: You know what they put on french fries in Holland instead of ketchup?
Vincent: I’ve seen ’em do it, man. They fuckin’ drown ’em in that shit.”
Vincent is right. We and the Belgians use mayonnaise on our French fries. And we are loving it. Give it a try when you are here.
