Ingredients

 * 1 lb spaghettini or capellini
 * 4 large garlic cloves, minced
 * 1/2 to 3/4 teaspoon dried hot red pepper flakes
 * 1/2 cup extra-virgin olive oil
 * Finely grated zest from 2 lemons
 * 3 tablespoons fresh lemon juice
 * 1 1/2 teaspoons salt
 * 1/2 teaspoon black pepper
 * 1/2 cup chopped fresh flat-leaf parsley

Directions
Cook pasta in a 6-quart pot of boiling salted water until al dente. Reserve 1 cup cooking water and drain pasta in a colander.

While pasta is boiling, cook garlic and red pepper flakes (to taste) in oil in a 12-inch heavy skillet over moderate heat, stirring, until garlic is golden, about 5 minutes. Stir in zest, then juice, salt, pepper, and 1/2 cup reserved cooking water and bring to a simmer.

Toss pasta in sauce with parsley. (Add more cooking water if pasta seems dry.)
