The closes I've come to a ripe Che Fruit

I've been growing this in ground for about 3 years now. The Che fruit. It has been a big disappointment. I think moving forward I'll dig it out and keep it in a pot in the greenhouse year round. It should help to ripen this fruit in time here in Seattle. Other wise this is the closes I've come to ripe fruit from the Che. It's still rock hard and inedible. The photo was taken in October.
