The correct expression is, "The proof of the pudding is in the eating". Proof here means test. So the expression means something like "We won't know until we try it"
Similarly, the expression "the exception that proves the rule" means the exception that tests, or challenges, the rule. it doesn't mean that an exception to a rule proves that a rule is true.
That would be stupid.
