From Maria Weingarten, November 2000
This dish is traditionally made with bucatini, also called perciatelli, which appear to be thick, round strands but are actually thin, extra long tubes. Linguine works fine, too. When buying pancetta, ask the butcher to slice it 1/4 inch thick; if using bacon, buy slab bacon and cut it into 1/4-inch-thick slices yourself. If the pancetta that you’re using is very lean, it’s unlikely that you will need to drain off any fat before adding the onion. Use 1 1/2 small (14 1/2-ounce) cans of diced tomatoes, or dice a single large (28 ounce) can of whole tomatoes packed in juice.
2 TBSP extra virgin olive oil 6 oz. Pancetta, ¼ inch thick sliced or
1 med. onion, chopped fine bacon, cut into strips 1 inch long and
½ tsp red pepper flakes or to taste ¼ inch wide
2 ½ cups diced tomatoes with juice Salt to taste
1 lb. bucatini, perciatelli, or linguini 1/3 cup grated Romano Cheese
1. Bring 4 quarts water to rolling boil in large stockpot or Dutch oven.
2. Meanwhile, heat oil in large skillet over medium heat until shimmering, but not smoking. Add pancetta or bacon and cook, stirring occasionally, until lightly browned and crisp, about 8 minutes. Transfer pancetta or bacon with slotted spoon to paper towel–lined plate; set aside. If necessary, drain all but 2 tablespoons fat from skillet. Add onion to skillet; sauté over medium heat until softened, about 5 minutes. Add red pepper flakes and cook to release flavor, about 30 seconds. Stir in tomatoes and salt to taste; simmer until slightly thickened, about 10 minutes.
3. While sauce is simmering, add 11/2 teaspoons salt and pasta to boiling water. Cook until pasta is al dente; drain and return pasta to empty pot.
4. Add pancetta to tomato sauce and adjust seasoning with salt. Add sauce to pot with pasta and toss over low heat to combine, about 30 seconds. Add cheese and toss again; serve.
