Do you have any information on the wonder egg plant? I can’t find anything on the Web except other people’s questions about it. It is grown from a seed inside one of those plastic two-part eggs and has some sort of edible fruits on it. I have seen it sold in drugstores in the past.
The plant you’re thinking of goes by the more formal name Solanum melongena and is a member of the eggplant family. The fruits, or “eggs,” cannot be plucked and eaten — they are very bitter. But you can prepare them in much the same way you would eggplants.
