Cacio e Pepe

Add the coarsely cracked black pepper to a dry, wide skillet — ideally one large enough to hold all the pasta later. Toast over medium heat for 60-90 seconds, stirring constantly, until the pepper is fragrant and just beginning to smoke at the edges. You should smell a warm, woody, almost floral intensity — distinct from raw pepper. Add the olive oil if using, swirl to coat. Remove from heat and let the pan cool slightly. The pepper is now bloomed and will perfume the entire dish. Do not clean the pan — the pepper stays.

Cook the pasta in a smaller pot of water than usual — less water means more concentrated starch in the pasta water, which is critical for the sauce. Use well-salted water but go slightly lighter than usual since the Pecorino is very salty. Cook to 2 minutes less than the package al dente time — the pasta will finish in the pan. Reserve at least 1 cup (240ml) of the pasta cooking water before draining. The water should look slightly milky and opaque with dissolved starch. Drain without rinsing.

While the pasta cooks, combine the finely grated Pecorino and Parmigiano in a bowl. Add 2-3 tablespoons of the hot pasta water to the cheese and stir rapidly with a fork to form a paste — it should look like thick spackle or a very stiff béchamel. This pre-hydration prevents the cheese from clumping into stringy knots when it hits the hot pasta. The paste should be smooth and pliable, with no dry lumps of cheese. If too thick, add a few more drops of pasta water. This step is the structural key to lump-free cacio e pepe.

Return the pan with the bloomed pepper to medium heat. Transfer the drained pasta directly into the pan. Add 3-4 tablespoons of the hot pasta water and toss vigorously with tongs for 1-2 minutes. The pasta should finish cooking in this starchy liquid, which will become slightly creamy as the starch from the pasta dissolves into it. The pan should be very active — continuous tossing creates the emulsification. When the liquid looks slightly creamy and most has been absorbed, remove the pan from heat.

Off the heat, add the cheese paste to the pasta in two additions, tossing energetically between each. Add pasta water a tablespoon at a time as needed to loosen the sauce — it should flow and cling simultaneously, not sit as a gummy solid. The combination of heat, starch, and fat will emulsify the Pecorino into a seamless sauce. Work quickly and continuously. If the sauce begins to tighten and clump, a small splash of hot pasta water and vigorous tossing will usually bring it back. Plate into warm bowls immediately. Finish with a final twist of cracked pepper and a dusting of grated Pecorino.
