Cooking

The raw fruit can have a somewhat bitter taste, but becomes tender when cooked and develops a rich, complex flavor. Traditionally, recipes would advise the salting, rinsing and draining of the sliced fruit (known as "degorging") to soften it and to reduce the amount of fat absorbed during cooking, but mainly to remove the bitterness of the earlier cultivars. Some modern varieties - including those large, purple varieties commonly imported into western Europe - do not need this treatment. The fruit is capable of absorbing large amounts of cooking fats and sauces, allowing for very rich dishes, but the salting process will reduce the amount of oil absorbed. The fruit flesh is smooth; as in the related tomato

). A recent (2008) study of a sample of 741 people in India (where eggplant is commonly consumed) found nearly 10% reported some allergic symptoms after consuming eggplant, while 1.4% showed symptoms in less than 2 hours.
Contact dermatitis from eggplant leaves and allergy to eggplant flower pollen have also been reported. Individuals who are atopic (genetically predisposed to hypersensitivity, such as hayfever) are more likely to have a reaction to eggplant, which may be because eggplant is high in histamine

s. A few proteins and at least one secondary metabolite have been identified as potential allergens. Cooking eggplant thoroughly seems to preclude reactions in some individuals, but at least one of the allergenic proteins survives the cooking process.

On 9 February 2010, the Indian Environment Minister, Jairam Ramesh, imposed a moratorium on the cultivation of Bt brinjal. His decision was made after protest from several groups responding to regulatory approval of the cultivation of Bt brinjal in October, 2009. Ramesh stated the moratorium will last "for as long as it is needed to establish public trust and confidence".
