You might as well as just leave it as long as you can to enjoy it on the plant, perhaps if you can time it right before the first frost you can cut them and bring them in to experience the disappointment first hand. They should still “ripen”, and you can eat the placenta, but it will be far from a pleasant fruit-eating experience.
