Galangal vs ginger
Close relatives in the same family that taste nothing alike. One is pine and citrus, the other is heat, and substituting either way changes a dish or a drink completely.

What is being compared
Why these get confused
Sold beside each other and often labelled 'Thai ginger', which is neither accurate nor helpful.
Point by point
| Aspect | Galangal | Ginger |
|---|---|---|
| Flavour | Sharp and pine-like with a soapy citrus note, and very little warming heat. | Warming, pungent heat with a clean bite and a faint sweetness behind it. |
| The rhizome | Paler, much harder, and impossible to grate — it is sliced or pounded. | Softer and juicier, and grates readily, which is how most kitchens use it. |
| Where it belongs | Tom kha, Thai curry pastes, Indonesian jamu and regional Southeast Asian infusions. | Almost everywhere: Europe, the Caribbean, East Asia, South Asia, as drink and as spice. |
| Fresh versus dried | Dried loses most of the pine character and is a poor substitute for fresh. | Fresh is brighter and dried is hotter; both are genuinely useful and not interchangeable. |
| In Europe | Familiar in medieval kitchens and almost entirely gone from European cooking by 1700. | Continuously present since the classical period and never left. |
The short answer
A Thai recipe calling for kha wants galangal and will be wrong with ginger. The reverse is equally true, and the two are not grades of one plant.
