Pureed Eggplant Soup with Tomato Relish
Ingredients
For the soup:
4 Tbs. olive oil
1 lb. eggplant (1 medium eggplant), sliced in half lengthwise
Kosher salt and freshly ground black pepper
5 cups homemade or low-salt canned chicken broth
8 large sprigs fresh basil
12 stems fresh parsley
2 sprigs fresh thyme
1 large onion, sliced (to yield 1-1/2 cups)
1-1/2 Tbs. minced fresh garlic
For the relish:
2 tsp. extra-virgin olive oil; more for garnish
2 tsp. minced fresh garlic
1/4 tsp. kosher salt
1 medium-size ripe tomato, peeled, seeded, and cut into small dice
1/2 tsp. sherry vinegar
1/4 tsp. freshly ground black pepper
2 Tbs. chopped fresh flat-leaf parsley
Preparation
Make the soup:
Heat the oven to 375°F. Spread 2 Tbs. of the oil on a rimmed baking sheet. Season the cut side of the eggplant with salt and pepper and put the halves face down on the pan. Roast until tender, about 40 minutes; a knife will enter the flesh easily. When the eggplant is cool enough to handle, scrape out the flesh with a spoon. Discard the skin.
Meanwhile, put the chicken broth, basil, parsley stems, and thyme in a large saucepan or a stockpot. Bring to a boil, reduce the heat, and simmer uncovered for 15 minutes. Strain the broth.
Heat the remaining 2 Tbs. olive oil in a large, heavy saucepan over medium heat. Add the onion and cook, stirring frequently, until golden and caramelized, about 20 minutes. Stir in 3/4 tsp. salt and the garlic. Add 4 cups of the stock, bring to a boil, add the eggplant flesh, reduce to a simmer, and cook for 5 minutes.
Ladle about 1 cup of vegetables and about half as much broth into a blender. Cover, but remove the center cap or keep the lid slightly cracked with the openeing away from you. Cover the lid with a folded dishtowel. Blend in pulses or on low speed at first, and then continuously until you have a completely smooth purée, adding more broth only if needed. With the blender on, carefully ladle in more vegetables and broth through the feeder hold, keeping the ratio about the same, until the blender is half full.
Strain the purée through a fine sieve set over a bowl, pressing it through with a rubber spatula. Purée and strain the remaining soup. Thin the soup, if necessary, so it has the consistency of heavy cream (you may not need all the broth).
