Spaghetti
A strand has no cavity and no ridges, so a sauce must coat it. Thin, slippery sauces win: oil and garlic, clams, a smooth tomato, a pecorino emulsion. A chunky ragu slides off and pools in the bowl. Rome dresses spaghetti with carbonara and cacio e pepe. Naples gives it clams and tomato.
Spaghettini
Less mass per strand means less sauce per mouthful, so the sauce should be light and fast. Oil, garlic, chili, lemon, clams, cherry tomatoes. Cream and ragu drown it.
