Oregano
Origanum vulgare
A hillside herb the Mediterranean dries by the bunch — pizza's soul, the line where Greek and Italian cooking braid together.
The rare herb that prefers to be dried.
Origin
Greek hillsides domesticated oregano so long ago the plant was already a culinary fixture in Homer. Oríganos — “joy of the mountain” — was bridal incense, medicinal infusion, and pizza topping in roughly that order across two thousand years. Greece, Turkey, and southern Italy still produce most of the world’s culinary supply.
The plant follows altitude. Mountain-grown oregano carries dramatically more carvacrol than valley-grown; this is why the Greek hillside variety reads sharper than the cultivated Italian. Mexican oregano, despite the name, is a different plant entirely (Lippia graveolens) — citrus-forward, less phenolic.

Sensory profile
Carvacrol and thymol are the dominant phenols, with a base of p-cymene. The ratio determines style: carvacrol-dominant oregano (Greek, Sicilian) reads “pizza-shop” — warm, almost medicinal. Thymol-dominant cultivars read closer to thyme, which is botanically next door.
Oregano is one of the few herbs that prefers to be dried. The fresh leaf is bright but lightweight; drying concentrates the phenolic oils and stabilizes the aromatic profile against heat. Italian and Greek kitchens almost never use fresh oregano; pizza, briam, and spanakopita expect the dried, slightly-crumbly leaf.

In the kitchen
Italian pizza Napoletana, insalata caprese (in some regions), Greek horiatiki salad, and Mexican birria and menudo all lean on oregano as a defining note. The dried herb is added late — sprinkled onto pizza after baking, into salad with the dressing, into stew during the last fifteen minutes. Long simmering boils off the carvacrol.

How to handle
Buy whole-leaf dried, not powder. Crumble between fingers just before adding to release the volatile oils. Greek kalamata oregano is the strongest grade; Sicilian and Calabrian are softer. Mexican oregano substitutes only loosely — use it for salsa and birria, not for pizza.
