Preparation
Preheat broiler. Place a large pot of salted water over high heat to boil.
Place a large skillet over medium heat with 2 tablespoons of butter. Add the onion, celery and carrots, season with salt and pepper, and cook until tender but not caramelized, 5-6 minutes. Add the potatoes, thyme, juice of the clams and 1/2 cup of water to the skillet and bring the liquids up to a bubble. Cover the pot, reduce the heat to medium and simmer until the potatoes are tender, 8-10 minutes.
While the veggies are simmering, drop the pasta into the boiling water and cook to al dente according to package directions. Just before the pasta is ready, reserve a large mug of starchy cooking water. Drain the pasta and return it to the pan it was cooked in.
