Grill the eggplants, turning them frequently until the skins become blackened and charred (or you can bake them in a slow oven for 1-2 hours until they become very soft).
Remove the eggplant skins and chop the flesh roughly.
Place the eggplant in a blender or food processor.
Add the garlic, lemon juice, tahini, extra virgin olive oil, cumin and pepper to taste.
Blend to a smooth paste.
Transfer to a serving bowl and drizzle with extra virgin olive oil.
Serve with fresh vegetables for dipping (e.g. celery and carrots) and toasted Lebanese or Turkish bread.
