This may very well be a Nordic kind of dip from the early seventies. Paprika was high fashion among the cooking savoir faire back then and you risked getting celery in dishes where they far from belonged. Probably because some local health guru had sworn to its many benefits.
I can even remember a tv ad proclaiming celery’s magnificence as snacks. With this dip you could actually end up dipping pieces of celery in a dip containing celery. I’ve said it before, those were hard times back then.
To make it even worse, the horrid disco music was lurking in the near future. A few years later you could actually risk sitting somewhere overdosing on celery listening to that horrible music. – Ted
