Pesto Genovese
“Genoese basil sauce — DOP basil, Sardo and Parmigiano, Ligurian pine nuts, garlic, oil, pounded in a marble mortar.”
Where it comes from
Codified in Giovanni Battista Ratto's La Cuciniera Genovese, 1863, though Ligurian basil-and-cheese paste predates it. Genoese DOP basil from Pra' has been protected since 2005; the consortium specifies seven ingredients only.
On the plate
Coarse green paste flecked with white cheese and pine-nut shards, glossy from oil. Sweet basil and pungent raw garlic up front, salty cheese mid, pine-nut fat coating the tongue. Tossed through trofie or trenette al dente, never warmed.
How it works
Marble mortar and wood pestle — metal blades oxidize basil and turn it black within minutes. Crush garlic and salt first to make a paste, then add basil leaves with rotating wrist motion (not pounding) to bruise cell walls without bruising chlorophyll. Pine nuts, then cheese, then oil drizzled in last.
DOP spec: Genovese DOP basil, garlic from Vessalico, Ligurian extra-virgin, Parmigiano Reggiano 30+ months, Pecorino Sardo, pine nuts (Pisa or Med), coarse sea salt — no other herb. The biennial Pesto World Championship at Palazzo Ducale Genoa has been held since 2007.
Variations
DOP Pesto Genovese (Pra' basil, mortar-pounded), Pesto alla Ligure (broader Liguria, looser cheese rules), Pesto Rosso from Sicily (with sun-dried tomatoes — actually pesto rosso, not Genovese), and the Recco-style cheese-heavy version pounded with extra Parmigiano.
