Spicy Roasted Indian Eggplant (Bhartha)

Preheat oven to 400 degrees F. Line a large rimmed baking sheet with foil.

Prick eggplants all over with a fork. Place on the prepared pan and roast, turning once or twice, until soft, 55 to 65 minutes. Cut open and let cool. Scrape the flesh onto a cutting board and chop. Discard the skin.

Meanwhile, heat oil in a large skillet over medium heat. Add onion and cook, stirring, until soft and starting to brown, 5 to 8 minutes. Add garlic, ginger and jalapeño; cook until starting to soften, about 2 minutes. Stir in cumin, salt, coriander, turmeric and crushed red pepper; then add tomatoes. Cook, stirring, until the tomatoes start to break down, 4 to 5 minutes. Add the chopped eggplant, cilantro, lemon juice and garam masala. Cook, stirring, until heated through, about 3 minutes more.
