The working recipe — the Market List, the Method, and where it lives or dies
I
Origin
Liguria
II
Description
The canonical Ligurian pesto made in a marble mortar — Genovese basil (DOP), Ligurian pine nuts, garlic, coarse salt, Pecorino Sardo and Parmigiano, emulsified with extra-virgin Ligurian olive oil. The mortar method produces a coarser, more aromatic result than a blender because it ruptures cell walls rather than cutting them, releasing volatile compounds without the heat that oxidises the chlorophyll.

The Thread
—Mortar-pounded basil, garlic and olive oil sauce — no cheese or pine nuts, but the same rupture-versus-cut emulsification philosophy → Pistou Provençal
—Mortar-pounded nut-and-pepper sauce — same cell-rupture technique used to extract volatile aromatics Catalan
—Mortar pounding of aromatic ingredients to release volatile compounds — same reason a mortar is required over a blender for maximum aroma Southeast · Asian
IV
Flavour Context
Intensely aromatic, grassy and sweet from the basil; pine nut richness; garlic sharpness; the olive oil binds it into something greater than the sum of its parts — one of the world's great sauces
