Linguine with Clams

In a large pot over high heat, bring 4 quarts of water and 2 tablespoons of kosher salt to a boil. Add the linguine and cook according to package directions until just shy of al dente. Drain in a colander (do not rinse), reserving ½ cup of the cooking water for the sauce.

Meanwhile, in a very large sauté pan over medium-high heat, heat the olive oil until hot but not smoking. Add the shallots and garlic and sauté until just golden, about 30 seconds.

Add the wine, red pepper flakes, ¾ teaspoon kosher salt, clams, and ¼ cup of the parsley; bring to a simmer and cook, covered, until the clams open, 6 to 8 minutes. Discard any unopened clams.

Add the pasta to the sauté pan with the clams. Increase the heat to medium and cook the linguine with the clams, tossing occasionally, until the pasta absorbs most of the sauce and is just tender, 1 to 2 minutes. If necessary, add some of reserved cooking water to keep moist. Remove the pan from the heat.

Add the butter, lemon zest, lemon juice, and the remaining 2 tablespoons of parsley; toss to coat. Taste and adjust the seasoning with more salt, lemon zest and/or lemon juice, if necessary. Transfer to a serving dish or bowls and serve.
