Cream masks the sharpness and character of the pecorino and transforms the dish into something else entirely. The creaminess of authentic cacio e pepe comes purely from the cheese-starch emulsion. Adding cream is like adding cream to carbonara. Don't.
The pasta or pan was still too hot when the cheese hit it. Make a slurry first — cheese whisked with warm pasta water — and add it only after pulling the pan off heat for at least 15 seconds. Finer grating also helps dramatically; microplane-fine is ideal.
No. Pre-grated cheese contains anti-caking agents (usually cellulose) that prevent smooth melting. Buy a block, grate it fresh, and get it as fine as possible.
Purists use only pecorino romano. Many Roman cooks use a 2:1 pecorino-to-parm blend to reduce saltiness and add roundness — that's what this recipe does. Both are defensible; the blend is more forgiving for home cooks.

Gricia is the common ancestor of amatriciana and carbonara — no tomatoes, no eggs, nothing added across the centuries. Four ingredients, one pan, and a technique you can nail on the first attempt.
Amatriciana is not a Roman sauce — it is from Amatrice, a mountain town 150 km northeast of Rome, and the formula is fixed: guanciale, San Marzano tomatoes, Pecorino Romano, dry white wine, peperoncino. No onion, no garlic, no cream. The recipe below follows the original closely.
Aglio e olio is Neapolitan, not Roman — the 'Roman' label stuck because English-language cookbooks needed a dateline and it sounds better than 'Campanian pantry pasta.' Whatever you call it, five ingredients and 20 minutes is the contract, and the technique is the whole job.
