SMOKY EGGPLANT SOUP

Steps:

• Poke 2 or 3 holes in eggplants with a paring knife, then place on a baking sheet under hot broiler, about 2 inches from flame. Cook for 3 or 4 minutes, allowing skins to blacken and char. Turn and cook on other side until eggplants have softened completely, about 4 minutes more. Set aside to cool, then remove and discard skins and roughly chop eggplant flesh.
• Meanwhile, put 3 tablespoons olive oil in a heavy-bottomed stainless or enameled soup pot over medium-high heat. Add onion, season generously with salt and pepper, and cook until softened and beginning to color, 5 to 7 minutes. Add garlic, cayenne and reserved eggplant and cook 1 minute more, then add broth and bring to a brisk simmer. Reduce heat and simmer gently for 10 minutes. Check seasoning of broth and adjust salt.
• Purée soup in batches in blender. Strain through fine-meshed sieve and discard solid debris and seeds. Add 3 tablespoons lemon juice to puréed soup and taste again, adding more as necessary. Soup should be well seasoned and rather lemony.
• Mix lemon zest with remaining 2 tablespoons olive oil for garnish. Ladle soup into small bowls, topping each bowl with 1 teaspoon lemon oil, 1/2 teaspoon za'atar and some chopped parsley. May be served hot or cold.
