They are irregularly shaped with a lumpy surface, and have rough, greenish-yellow skin with occasional dark red streaks on the side that got sun. That skin is covered with grey, black russeting.
Inside, though, the finely-textured, off-white flesh is crisp, and has a sweet, very rich, full flavour.
The fruit ripens in England in October.
