The best shapes for vodka sauce
Tomato and cream brought together with a splash of vodka, which helps two things that separate on their own hold as a stable pink emulsion. Italian-American, and the vodka is doing chemistry rather than adding flavour.
Tomato and cream emulsified into a clinging pink coat. It films everything but shines where ridges hold a thicker layer.
Italian-American by adoption, 1970s-80s menu history. Canonical: penne.

The geometry is built around catching sauce.

A fusillo is a ribbon twisted into a helix, so sauce does not just coat it, it lodges in the grooves between the turns.

The diagonal cut is functional, not decorative.
What we would not put it on
Delicate fresh egg strands. The emulsion is heavy enough to overwhelm them, and they tear under it before they reach the fork.
