I guess I should re-state - "times AND TASTEBUDS change".
When I was a kid, cheese was not a plentiful thing - there were not many types available, and it was quite expensive. It was doled out in small quantities - usually with a bowl of soup & a few crackers for lunch. I do remember that it often used to go mouldy on the outside - my mom would slice all that off & we'd continue eating ... today, I think that's frowned upon.
Definitely cheez whiz with celery pinga!! And velveta for 'cheese dreams' at Sunday lunch.
