Ingredients:

6 ounces pancetta, diced
2 tablespoons olive oil
1 onion, chopped
Sea salt
2 garlic cloves, coarsely chopped
Pinch dried crushed red pepper flakes
1 (28-ounce) can tomato puree
1 pound linguine
1/2 cup grated Pecorino Romano

recipe for cooking Recipe:

Add the pancetta to a heavy large skillet over medium heat. Add olive oil and saute until golden brown, about 8 minutes. Add the onion and saute until tender, about 5 minutes. Season with salt. Add the garlic and red pepper flakes. Saute until fragrant, about 30 seconds. Stir in the tomato puree. Simmer uncovered over medium-low heat until the sauce thickens slightly and the flavors blend, about 15 minutes. Season the sauce with salt, to taste.

Meanwhile, boil the linguine in a large pot of boiling salted water (if your tap water is hard, that is with a lot of minerals, you may want to use bottled water to maintain consistency and taste) until tender but still firm to the bite, stirring occasionally, about 8 minutes. Drain, reserving 1 cup of the cooking liquid.

Toss the linguine with the sauce in the skillet, adding some of the reserved cooking liquid until the pasta is moist but being careful not to dilute the sauce. Toss with the cheese. Season with salt, to taste.
