White Eggplants - you might want to consider one of the egg shaped varieties. Some people say there is a taste difference - white eggplants being a bit milder and fruitier - personally I don't discriminate based on color and don't really see much of a difference in taste - so once you go black - sure you'll go back [and forth]. In the eggplant realm the whites are the minority, but a novel deviation.
The absolute best of the full sized White Eggplants in my opinion is Casper Eggplant. It's taste is undeniably different, not just a subtle difference but a scrumptious variation. If you've ever read anything about these eggplants, you'll see them being described as tasting like mushrooms, and that is perhaps the best way to describe them. They actually do taste like Mushrooms - certainly don't taste like chicken.
Cloud 9 Eggplant is a prolific hybrid white eggplant. The fruits are between 5 and 8" long. Cloud 9 produces more prolifically and is easier to maintain than Casper, but the taste is not as good. It's still a good eggplant comparable in taste to most standard varieties.
Ghost Buster Eggplant is a hybrid White Eggplant very similar to Casper. They grow 6-8 inches in length and are fat and oval. It is very thick skinned and the skin should be removed before cooking. It is sweeter than purple and black varieties but can't compare to Casper in this department.
Gretel is another popular white variety. It produces clusters of glossy white Eggplants that are harvested at 3-4" in length.
A few other white varieties include "Blanche aubergine", also known as Albino, "White Beauty," and "Tango"
Easter Egg eggplants can be considered a white variety, but they also produce multi-colored egg shaped fruits and are listed further down on this page under Exotic varieties. Read More on White Eggplants at White Eggplant Varieties
