Linguine con Vongole is one of those pasta dishes that you can find basically anywhere in coastal Italy. Mysteriously, in the States, it is often presented cloaked in a tomato-based sauce, not how you'd find it in Italy (though they might throw in a handful of fresh chopped tomatoes at the end). The pasta and clams come generously brothy, and I love to fai la scarpetta (sop up the sauce with a piece of bread).
Fill a large pot with water and add enough salt so the water tastes like seawater, and bring to a boil. Add the pasta and cook according to the directions on the package until 2 minutes shy of al dente.
Meanwhile, heat the olive oil over medium heat in a large saute pan until shimmering. Add the garlic and cook, stirring, until golden, about 1 minute.
Add the cockles, red pepper flakes and white wine and shake to combine. Cover and cook until the cockles open, 4 to 5 minutes. Remove the lid and discard any cockles that haven’t opened (those are dead).
Drain the pasta and add it to the pan with the cockles. Cook, tossing to combine, until the pasta is al dente and absorbs some of the clam juices.
Add the butter and parsley and shake the pan to combine.
Season to taste with salt and black pepper and serve immediately with slices of bread on the side to sop up the juices in the bowl.
