Fresh ginger root is an aromatic, pungent spice, used in the bar for juice, muddled flesh and syrup.
Ginger syrup gives the flavor with sugar attached and no fresh bite. A strong ginger beer brings heat, sugar and gas together, which suits a long drink and ruins a short one. Dried ground ginger is hotter and flatter, a small pinch at a time.
Dried ground ginger
Drying turns the root’s gingerols into shogaols, so dried ginger burns differently and lacks the fresh citrus edge. It is not a measure-for-measure substitute in anything.
Galangal
A related rhizome, sharper and piney, familiar from Thai cooking. It is easy to pick up by mistake at the market, and they taste nothing alike — in a drink it reads medicinal where ginger reads warm.
Whole and unpeeled in the fridge it keeps a couple of weeks and shrivels instead of rotting. Cut or peeled it dries out in days. It freezes indefinitely and grates straight from frozen, which is the easiest way to keep it if you use it in small amounts.
