With a fork pierce the eggplant on all sides. Cover with aluminum foil and place on oven rack. Bake at 400°F for 1 hour or until completely soft. Let cool. When cooled a bit, slice eggplant in half and scoop out inside of eggplant. For the recipe set aside ¾ cup of the eggplant.
In a food processor or blender blend garlic, egg and lemon juice. Blend very well. Gradually add oil in a thin stream until it emulsifies (like a mayonnaise consistency). Season with salt. Add ¾ cup eggplant filling. Blend well. Add more lemon juice and salt to taste. Season with a bit of crushed black pepper.
Notes
Do not add more than 1 tbsp of lemon juice in the beginning or the mixture will not emulsify well. When everything is done then add more lemon juice to your liking.
