"According to William Woys Weaver in his book Heirloom Vegetable Gardening, 'Old White Eggplant' was the earliest type to reach England, back in the 1500s. This was an ornamental variety with fruit that resembled a chicken egg"
Egg plants first came from the Indian subcontinent, FYI.
It's one of those things you never really think about until someone asks the question..it happened to me last week during lunch with a friend.
I used to hate them, but like many things in life, my tastes have changed. :D
