Honeydew melon by John Spottiswood.

These large, choice melons have either green or orange flesh. As honeydews ripen, they turn from green to creamy white to yellow. Avoid green ones, but a creamy white one will (unlike other melons) ripen on your counter in a few days. A perfectly ripe honeydew will yield just a bit to pressure at the blossom end and have a sticky, velvety rind.
