Finish with lemon juice, to taste, and remaining parsley. Eat right this very second.

If you think your clams may not be clean, wash them first: Fill a large bowl with cool tap water and place the clams in it. Let them soak for 20 minutes during which they’ll expel any sand and grit.

Bring a large pot of very well-salted water to a boil and cook linguine until it is tender but still with a good bite left to it, about 1 minute less than the final doneness you’d prefer. Carefully ladle out (about) 1 cup of pasta water into a glass or bowl, set aside. Drain pasta, discarding remaining cooking water.

In your empty pasta pot or a large sauté pan with a lid, drizzle oil in empty pot and add garlic, a couple pinches of pepper flakes (up to a teaspoon is great here for people who like more heat), and kosher salt, I use about a teaspoon here but use less if you’re nervous. Turn heat to medium, stirring the garlic and pepper flakes until the garlic begins to sizzle and just barely begins turning golden brown. Add wine and half of reserved pasta water and turn heat up so that it boils. Add clams (discarding the water they were soaking in) and cover pot to steam them open. Manila clams take 3 or so minutes to steam open; cherrystone and/or little neck can take up to 5 to 7 minutes. Peeking under the lid is fine.

Scoop cooked clams into a large bowl with a slotted spoon, discarding any that don’t haven’t opened, and leaving the cooking liquid behind. Simmer the cooking liquid in the pot until it has reduced slightly; you want a little less than cup. Taste for seasoning; adjust as needed. Add butter and, once it has melted, add drained linguine and half of parsley; cook them together for 1 minute, tossing frequently, until linguine is well-coated and only a little liquid remains at the bottom. If needed, use some or all of remaining pasta water to keep pasta loose. Add clams (and any liquid that has collected in the bowl) to the pot and toss to combine, once or twice, then tip whole mixture into serving bowl.
