- 1 large eggplant (about 2 pounds), cut into 1-inch cubes
- Kosher salt
- 6 celery ribs, cut into 1-by-1/4-inch matchsticks
- 1/2 cup plus 3 tablespoons extra-virgin olive oil
- 3 garlic cloves, finely chopped
- 6 basil leaves, finely chopped
- One 28-ounce can crushed tomatoes
- 1 large onion, very finely chopped
- 1 cup pitted green olives, thinly sliced
- One 3-ounce bottle brined capers—drained, rinsed and patted dry
- 1/2 cup white wine vinegar
- 3 tablespoons sugar
- In a colander set in a large bowl, toss the eggplant with 1 tablespoon of salt. Let drain for 45 minutes, tossing occasionally. Spread the eggplant on a paper towel-lined baking sheet and blot dry.
- Meanwhile, bring a medium pot of water to a boil and fill a medium bowl with ice water. Add the celery to the pot and blanch for 30 seconds, then drain and plunge immediately into the ice water. Let chill for 5 minutes, then drain and pat dry.
- In a large saucepan, heat 3 tablespoons of the oil. Add the garlic and basil and cook over moderately high heat, stirring, until fragrant, about 1 minute. Add the crushed tomatoes and bring to a simmer. Reduce the heat, cover and simmer for 30 minutes, stirring occasionally. Uncover and cook until slightly reduced, about 10 minutes longer. Remove from the heat and season with salt.
- In a large skillet, heat 1/4 cup of the oil. Add the eggplant and cook over moderately high heat, stirring occasionally, until golden and tender, about 12 minutes. Transfer to a bowl.
- Wipe out the pan and heat the remaining 1/4 cup of oil in it. Add the onion and cook over moderately high heat, until translucent, scraping up any browned bits stuck to the bottom of the pan, about 2 minutes. Reduce the heat to low and cook, stirring occasionally, until soft and lightly caramelized, about 13 minutes. Add the tomato sauce, blanched celery, olives, capers, vinegar and sugar. Bring to a simmer and cook over moderately high heat for 5 minutes, stirring occasionally. Add the eggplant and cook, stirring, until the caponata is thick, about 5 minutes longer. Remove from the heat and let cool slightly. Serve warm or at room temperature.
The caponata can be refrigerated for up to 3 days. Bring to room temperature or warm slightly before serving.
