The great debate between my roommate and I. Is peanut butter salty or sweet? She votes salty, I vote sweet. I keep hearing from those that agree with her that peanuts, are salty, therefore peanut butter is salty. I remind them that salted peanuts are salty, and that is not what is in question. The peanutty taste. If you HAD to classify it under Salty or Sweet, which would you go with.
