My missus and I are enjoying our first Cara Caras ("blood" navel oranges) of the Oz winter.

They are so nice tasting, and even have a wonderful delicate perfume before you cut them. We wait impatiently each winter for them to appear at our local fruit shop.
Sorry, no photos (but they have a slightly reddish tinge to the flesh, with a normal orange colour skin)
