Cacio e Pepe
Spaghetti finished in a sauce of pecorino romano and coarse black pepper, no butter or cream in the traditional version. Starchy pasta water pulls the cheese into an emulsion that clings to the noodles rather than sitting on top.
Where it comes from
Roman shepherds are said to have carried aged pecorino and dried pasta on long treks because both kept without refrigeration, with black pepper added to warm a simple meal. No document fixes when this started; the ingredients themselves suggest travel food more than a restaurant dish.
What cooks argue about
The dish turns on temperature: cheese in water too hot seizes into clumps, too cool and it won't melt. Cooks split over a cold cheese-water slurry versus adding hot pasta water straight to the cheese.
