Dried thyme

Dried thyme is the leaf and flowering top of Thymus vulgaris, the common garden thyme of the Mediterranean basin, supplemented in commerce by Thymus serpyllum (wild or creeping thyme, broadly distributed across temperate Europe) and Thymus citriodorus (lemon thyme, a hybrid prized for its citral-dominant aroma). The volatile signature of commercial T. vulgaris is thymol at thirty to fifty percent of essential oil, paired with p-cymene, carvacrol and linalool; the chemotype matters at purchase, because thyme is one of the most polymorphic herbs in the kitchen, with at least six recognised wild chemotypes (thymol, carvacrol, linalool, geraniol, alpha-terpineol and trans-thujanol) that taste measurably different. Provencal thyme leans thymol-carvacrol and reads medicinal and sharp; Spanish Sierra de Segura thyme skews carvacrol-heavy and darker; Moroccan Middle Atlas thyme carries more linalool and a softer, almost floral mid-palate. The herb is a structural ingredient rather than a finishing one: it underwrites the French bouquet garni alongside bay and parsley, anchors the Levantine za'atar blend with sumac and sesame, sits inside pates and terrines where its thymol survives seventy degrees of slow cooking, and sings on roast chicken, lamb shoulder, white beans and provencal vegetable gratins. Good dried thyme retains a grey-green colour and releases oil visibly when rubbed between fingers.
