Galangal paste

Kulanjan

5 g1 teaspoon

15 g1 tablespoon

Paste density ~1.0 g/ml; 1 tbsp = 14.8 ml ≈ 15 g, so 5.0 g/tsp.

Instead of Galangal paste

Nothing truly replaces galangal's piney, citrus-like aroma; ginger is the closest everyday option.

Ginger paste
Use the same weight; it is sharper and less citrusy, so reduce any other ginger in the recipe slightly.
Fresh ginger
Grate the same weight and crush to a paste; the flavour will be more pungent and less piney.
