Golden raisins give this pasta dish a hint of sweetness, which balances out the slightly bitter taste of escarole.
In a large (8-to-10-quart) pot of boiling salted water, cook pasta 10 minutes. Add escarole and raisins; cook 2 minutes. Reserve 1 cup pasta water; drain. Set aside.
Dry pot. Place oil, pepper flakes, and garlic in pot. Cook over medium heat, stirring occasionally, until garlic is fragrant, 1 to 2 minutes. Remove from heat; toss in pasta mixture with Parmesan and reserved pasta water. Season with salt and pepper. Stir well and serve.
You may substitute kale or chard for the escarole.
