Batali'S Simple Penne All'Arrabbiata - cooking recipe

Ingredients

3 tablespoons kosher salt
4 tablespoons extra virgin olive oil
1/2 cup tomato paste
1 tablespoon hot red pepper flakes
1 1/2 cups tomatoes, chopped (like Pomi)
1 lb penne pasta
coarse sea salt, to taste (preferred brand ( Maldon)
4 tablespoons extra virgin olive oil
parmigiano-reggiano cheese, freshly grated

Preparation

Bring 6 quarts of water to a boil in a large pot, and add 3 tablespoons kosher salt.
Meanwhile, put 4 tablespoons olive oil in a large saute pan over medium heat. Add the tomato paste and pepper flakes. Reduce the heat to low and stir just until fragrant, about 4 minutes.
Stir in the tomatoes, and remove from the heat.
Drop the pasta into the boiling water, and cook until al dente. Drain the pasta, reserving 1/4 cup of the pasta water.
Add the pasta and the reserved pasta water to the tomato sauce, stir and toss over medium heat until the pasta is well coated.
Season with salt if necessary, then add 4 tablespoons olive oil, tossing well.
Serve immediately, with freshly grated Parmigiano-Reggiano cheese on the side.
