b'WHAT YOU NEED TO DO:Bring a large pot of salted water to a boil, add the pasta, and cook for 8 to 10 minutes or until tender yet firm (as they say in Italian, al dente). Drain the pasta well, reservingcup of the starchy cooking water. Meanwhile, heat the olive oil in a deep skillet over medium heat. Add the pancetta and saut for about 3 minutes, until it is crisp and the fat is rendered. Toss the garlic and onion into the fat and saut over medium-low heat for 3 to 4 minutes to soften. Add the red pepper flakes.'
