Fresh ginger root is the fresh, unprocessed rhizome of Zingiber officinale, used as an aromatic, pungent spice.
Sharp and warming, with a bright, faintly citrusy pungency and a fresh, peppery bite.
A few slices or a small knob is muddled, juiced, or infused to drive aromatic heat into a drink; it works either as a defining flavour or as a small accent, dosed to the intensity wanted.
Only another form of the same rhizome — dried, ground, or preserved ginger — approximates the aromatic pungency, and even then only when ginger is a background accent; when the fresh rhizome is the drink's defining flavour, no processed form and no unrelated aromatic replaces it interchangeably.
Dried/ground ginger
Drying converts the rhizome's gingerols to the more pungent shogaols, making dried ginger sharper and hotter with a less fresh, less citrusy character than the fresh rhizome.
Galangal
Galangal is a different rhizome in the same family, with its own distinct, sharper and more piney aroma; it is not the same plant as ginger.
Cut from the underground stem of a herbaceous tropical perennial in the family Zingiberaceae, the rhizome is used fresh — as opposed to being dried, ground, or preserved in brine, vinegar, or sugar syrup.
Store the fresh rhizome refrigerated or in a cool place and use before it softens and dries out.
Ginger originated in Maritime and Southeast Asia, native to humid tropical and subtropical forest habitats; it is unknown in the wild and exists only in cultivation.
