Japanese eggplant, botanically classified as Solanum melongena, belongs to the Solanaceae or Nightshade family, the purple variety. The name Japanese eggplant is used as a general description of different varieties of eggplant grown in Japan.

The eggplant is elongated and slender, with an average length of 20 to 25 cm, and a rectangular to a cylindrical shape, slightly wrinkled at the edges. The Eggplants can appear curved or straight and are bound with a green or dark purple stem depending on the variety. These Japanese eggplants come in a variety of shapes, from oblong and slender to oval.

The skin is thin, smooth, shiny and delicate, easily damaged and its color ranges from light purple to dark purple, almost black. The creamy flesh is green in color and almost seedless with a dense, firm and spongy texture.

How to cook Japanese Eggplant

Japanese eggplant has a mild sweet taste that is suitable for cooking applications such as sauting, pan-frying, deep-frying, grilling and baking.

Eggplant has a thin skin that is left in the cooking process, and the flesh has a porous nature, which easily absorbs the accompanying flavors. Japanese eggplant also retains its purple-tinted skin, adding vibrant color to fried or roasted side dishes.

Eggplants are popularly grilled to develop a smoky flavor, or grilled pieces are thrown into salads for depth of flavor. In addition to grilling, Japanese eggplant can be fried as a side dish with spices, mixed into food as a meat substitute, dipped or added to vegetables.

Eggplants can be cut in half or sliced, braced into delicious-sweet, rich sauces, or pickles can be made for long use and eaten as a tangy snack. Japanese eggplant is traditionally grilled. Eggplants are also deep-fried and served in soy sauce.
