BAKED PENNE WITH GREEN CHILES

Steps:

• Preheat the oven to 500°F (260°C), with a rack in the middle position. Bring a large pot of water to a boil over high heat. Meanwhile, in a 13 by 9-inch (33 by 23-cm) baking dish, stir together the milk, cream, tomatoes, chiles, Cheddar, and mustard. Season with 1 teaspoon salt and some pepper, then set the tomato mixture aside.
• When the water boils, season it generously with salt; it should taste like seawater. When it returns to a boil, add the pasta, quickly stir to separate the noodles, then cover the pot. When the water returns to a boil again, uncover and boil the pasta until very al dente, stirring occasionally.
• Drain the pasta thoroughly, then pour the noodles on top of the tomato mixture and toss to combine. Gently "shake" the dish to distribute the ingredients, then top evenly with the Pecorino.*
• Bake until bubbling and lightly browned, about 12 minutes. Let rest for 5 to 10 minutes before serving.
