more than likely ... i know that's why i liked tomato catsup when i was younger ... i'm not so much a fan of it any more ...

I had to google the above but it sounds like thats what we call relish

Funny hey how Different countries call the same things different things

where are you from?
i ave never heard about banana ketchup, even if i would love to taste it.
In my country only tomato ketchup is available and is widely used, because is very tasty; perhaps the banana ketchup would be the same.
