Let's cook
Use less water than usual
Cook the pasta in a wide pan with just enough water to cover. Less water means far starchier water, and the starch is what makes the sauce work.
💡This is the trick nobody mentions. Starchy water is non-negotiable.
Toast the pepper
Coarsely crush the peppercorns and toast them in a dry pan for 60 seconds until fragrant. Add the olive oil and a ladle of pasta water and let it bubble.
Grate finely and let it warm
Grate the pecorino as finely as you can and let it come to room temperature. Cold, coarsely grated cheese seizes into strings instantly.
Make a cheese paste
Mix the pecorino with a few tablespoons of warm — not boiling — pasta water in a bowl until it forms a smooth, thick paste.
💡Boiling water will scramble the cheese. Let the water cool for 30 seconds first.
Combine off the heat
Drain the pasta 1 minute early and add it to the pepper pan off the heat. Add the cheese paste and toss hard, adding pasta water bit by bit, until a glossy sauce coats every strand.
Serve at once
Plate immediately with more pepper and pecorino. It stiffens as it cools and cannot really be rescued.

📝 Tips, swaps, and make-ahead notes
The two failure modes are clumping (cheese too cold, or water too hot) and wateriness (not enough starch, or not tossed hard enough). If it clumps, take the pan fully off the heat, add a splash of cool pasta water, and keep tossing.
- •Do not substitute: Parmesan behaves differently and gives a grainier sauce; pecorino romano is the right cheese.
- •Insurance: A teaspoon of cornstarch whisked into the cheese paste makes the emulsion far more forgiving.
- •Scale carefully: This is much harder to make for eight than for four. Cook two separate batches.
