You can use fresh clams and serve them in the shell with the pasta or you can buy fresh chopped or frozen clams if you have a good source. I can get clams shelled with their juices, which I like so I can just plow right through this when eating. No time for picking clams out of shells!

box spaghetti, linguini dry pasta
extra-virgin olive oil
garlic cloves, finely chopped
teaspoon red pepper flakes
pounds littleneck or Manila clams, scrubbed and rinsed well or 1 cup chopped clams fresh or frozen
kosher salt and freshly ground black pepper
fresh flat-leaf parsley
parmigiano reggiano (optional)
Prep the Ingredients Chop two large cloves garlic. Chop handful of parsley, about two tablespoons worth. Cube about ½ cup of pancetta. If using clams in shell, scrub and rinse sand from shells. If using chopped clams, pick through to make sure there aren’t any shells. If using frozen chopped clams, place in a strainer and run under cold water to defrost. Boil the Pasta Bring a large pot of salted water to a boil, add ½ box of pasta and cook for 8 minutes or until "al dente”. Make the below sauce while waiting for pasta to boil so you can strain the pasta and place it directly into the below pan with the sauce. Make the Sauce Place a large pan with sides on medium heat. Add a touch of olive oil and place the pancetta in the pan and brown both sides, about two minutes each side. Take the pancetta out of the pan and reserve on paper towels. Drain the fat from pan. Place pan on medium heat and add a decent amount olive oil to the pan, about 1/8 cup. Place chopped garlic, a sprinkle of chili flakes to the pan. After a minute, add the clams to the pan. If you are using chopped frozen or fresh, season with salt, pepper and lemon juice and sauté for only one minute. (If using clams in shell, add the clams after sautéing garlic, along with squeeze of lemon juice . Cover and cook, shaking the pan periodically, until all the clams are opened, about 7 minutes. Discard any that have not opened.) Finish the Dish Crank the sauce up to medium-high heat. Add the hot, drained linguine to the pan and season with salt and pepper. Toss the pasta with the clams and olive oil sauce so it's nicely coated. Add a handful of chopped parsley. Drizzle with a splash of olive oil before serving and if you are not interested in being traditional, a handful of parm cheese.
