Toast crushed black pepper in a dry skillet over medium heat until fragrant, then loosen it with 120 ml reserved pasta water. · 2 min
What to look for: Pepper smells aromatic and the water bubbles lightly

What to look for: The cheese mixture is smooth, thick, and free of large clumps
- Emulsify Sauce

Ingredient substitutions
Spaghetti
- Tonnarelli: Traditional in Rome and excellent for holding the cheese sauce
Pecorino Romano
- Extra aged Pecorino Romano: Use only Pecorino Romano for an authentic sharp and salty profile
Black pepper
- Finely ground black pepper: Use slightly less because fine pepper tastes sharper
Salt
- Fine sea salt: Measure carefully because fine salt is denser
Pasta water
- Hot water: Less authentic and less starchy, so the sauce may be thinner
