Rome's egg-and-guanciale miracle: no cream, ever. The sauce is yolks and pecorino emulsified by pasta heat and rendered fat — a knife-edge technique worth mastering.

Prep checklist
Guanciale — or pancetta, in batons
Eggs — 2 yolks + 1 whole
Pecorino Romano — finely grated
Whole Black Peppercorns — toasted and cracked
Spaghetti — the sauce's vehicle
4 steps
Method
1
Render the guanciale in a cold pan brought to medium until glass-crisp, 6–8 minutes. Kill the heat; leave the fat.
7 min — timer available in cooking mode
2
Whisk eggs, pecorino, and pepper into a thick paste. Boil the spaghetti in modestly salted water (the pork and cheese are salty) until al dente.
Why this works
Modest salt is deliberate — this is the one pasta water you under-salt.
3
Drag the hot pasta into the warm (not hot) pan of fat with tongs, bringing splashes of pasta water. Toss 30 seconds off the heat.
4
Add the egg paste and toss relentlessly, adding pasta water spoon by spoon, until it turns to glossy cream that coats every strand. The pan's residual heat cooks the egg to silk — direct flame scrambles it.
Why this works
If you can see liquid egg, keep tossing. If you see scrambled bits, the pan was too hot — next time, cooler pan, more motion.
From the pass
Chef's notes
Taste before serving and adjust salt and acid — the last 30 seconds of seasoning matter more than any single ingredient.
When it goes sideways
Common mistakes
Scrambled eggs
Pan too hot when the eggs went in. The sauce finishes OFF the flame on residual heat — brave cooks even do the final toss in the mixing bowl.
Gluey and tight
Not enough pasta water. The starch-water is the loosener; add it hot, a spoonful at a time.
Afterwards
Keep, reheat & pair
Storage
Airtight jar in the fridge, 3–5 days. Press plastic wrap onto the surface of starch-thickened sauces to stop a skin forming.
Freezing
Most sauces freeze 2–3 months; freeze in ice-cube trays for single portions. Emulsified butter/egg sauces don't freeze — they break on thawing.
Reheating
Reheat gently over low heat, whisking; butter- and egg-based sauces split when boiled. Loosen with a spoonful of warm water or stock.
Make ahead
Most sauces keep 3–5 days refrigerated and freeze in ice-cube trays for instant single portions. Emulsified butter sauces are best made within the hour.
