The long thin eggplants, typically green in color, are known as the Thai Green eggplants, which grow up to 12 inches in length. With a thin skin and a mild flavored flesh, the Thai Green eggplant is a very common Asian egglant. While some varieties of Thai eggplants are long and oblong shaped, others may be small, round and stocky. The small round eggplants are often referred Thai Kermit eggplants or as Garden Eggs and Bitter Balls, names often associated with a similar eggplant from Africa. Since Thai eggplants are highly perishable, store in a refrigerator for a week or less. They become increasingly bitter as they age.
