Cacio e pepe is Rome's three-ingredient pasta: tonnarelli or spaghetti tossed in a creamy emulsion of grated pecorino romano, pasta water and crushed black pepper. Nothing more.

Cacio e pepe predates carbonara by centuries. Shepherds in the Lazio mountains carried pecorino romano, black pepper and dried pasta on long transhumance routes from the 1700s onward; the three ingredients kept and combined into a hot meal at any inn. The Roman bistro form emerged in the 19th-century working-quarter trattorias. The dish has only three ingredients and zero margin for error: the emulsion must be glossy, not lumpy. Tonnarelli (Lazio's egg-pasta cousin to spaghetti) is the canonical shape. Da Cesare al Casaletto serves the famous fried-cup variation; Felice a Testaccio's table-side toss is the classic Roman service ritual.

Tip from the editors. The pecorino must be at room temperature, not cold from the fridge. Use less pasta water than feels right; the cheese needs heat and motion to emulsify, not flood.
