The best shapes for pesto genovese
Basil, pine nuts, garlic, parmigiano and pecorino, and olive oil, pounded together raw and never heated. Heat is what turns basil dark and dulls it, so the sauce meets the pasta warm at most, thinned with a little cooking water.
Raw basil and oil, never cooked. The fine solids want texture to grip, Liguria mandates trofie or trenette with potatoes and green beans, and the twist of a curl holds the leaf flecks.
Canonical: trofie, linguine, trenette.
The embossed relief is the point.
The hollow inner curve scoops and holds sauce while the ruffled crest and light ridges along the outside catch whatever coats them.
The pinch does the work.
A fazzoletto is a wide, very thin sheet, so it presents a large flat face to its dressing rather than a groove or a twist to trap it.
The flat leaf body offers broad surface for a sauce to cling to, while the raised central ridge and slightly thicker curved edges give the strand structure and grip.
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 helix works like fusilli with the volume turned down.
A linguine strand is an oval, not a circle, so it lays two flat faces against a sauce instead of one curved line.
Treat orzo as a grain that happens to be pasta.
The twist is the working part.
A wide flat ribbon gives sauce more landing area per strand than any round noodle.
The twist is the working part.
The broad spiralling ruffle and circular folds create deep pockets that trap thick, chunky sauce against the central core.
What we would not put it on
Wide smooth tubes. The fine leaf flecks need drag to stay put, and on a slick wall they wash off into the bottom of the bowl.
