Ingredients

  • 50 grams salted butter (it's a simple sauce, so opt for the good stuff if you can)
  • 3 tablespoons extra-virgin olive oil
  • 3 to 5 garlic cloves, smashed and chopped
  • 5 anchovy fillets (I like Ortiz anchovies from Cantabria, packed in olive oil)
  • 1/2 lemon, juiced (or more, depending on your taste), plus zest for garnish
  • 300 grams spaghetti
  • Freshly ground black pepper, to taste
  • Freshly grated Parmesan cheese, to taste

Method

  • Set large pot of generously salted water over high heat.
  • While waiting for water to boil, add butter and olive oil to a large pan over medium-low heat. When butter is melted, add garlic. You may want to turn the heat down-nothing ruins flavor like burnt, bitter garlic!
  • Once garlic is golden, add anchovy fillets and smash using a flat wooden spatula. Stir occasionally until mixture is more or less uniform. Think of this as a rustic sauce-no need to be perfectly smooth. Add the lemon juice and stir.
  • Lower heat, and while sauce continues to cook, add pasta to water, and cook until not quite yet al dente.
  • Here's a trick I learned from working at a culinary school: To fully coat every single noodle with sauce, finish pasta in the sauce pan, mixing continually to soak up all that saucy flavor. And because your sauce will get creamy with a little bit of that starchy pasta water, I ditch a colander altogether and use tongs (plus maybe a wooden spatula for support). Scoop pasta directly from the water into the sauce pan. Alternatively, you can strain pasta and reserve a half cup of pasta water, then add that to your sauce. But I'm all about less mess.
  • When the pasta is well coated and cooked to your liking, garnish with fresh ground pepper, a touch of lemon zest, and grated Parmesan.
