Most commonly purple, the spongy, absorbent fruit is used in several cuisines. Although often considered a vegetable, it is a berry by botanical definition. As a member of the genus Solanum, it is related to tomato and potato. Like the tomato, its skin and seeds can be eaten, but, like the potato, it is usually eaten cooked. Eggplant is nutritionally low in macronutrient and micronutrient content, but the capability of the fruit to absorb oils and flavors into its flesh through cooking expands its use in the culinary arts.
