Making Thai Red Curry Paste from Scratch
Commercial pastes often lack the raw, sharp edge of fresh roots. Building your own requires patience with the pestle but rewards you with a depth of color and heat that defines the dish before it even hits the heat.
The texture is everything.
Do not be tempted to use a food processor; the blades will heat the ingredients and turn them into a watery puree rather than a thick, fragrant paste. You need the gravity and crushing force of a heavy granite mortar.

What goes in.
- 10dried spur chilies, soaked in warm water for 15 minutes
- 1 tspkosher salt
- 2 tbsplemongrass, finely sliced (only the bottom 3 inches)
- 1 tbspgalangal, finely minced
- 1 tspkaffir lime zest, minced
- 2 tbspshallots, finely chopped
- 1 tbspgarlic, minced
- 1 tspshrimp paste
Order matters for friction
Always start with the driest, toughest ingredients—the chilies and salt—to create a base grit. Add fibrous roots like lemongrass only after the chilies have broken down, as they act as a natural abrasive to help grind the others into a fine paste.
The method.
Crush the chilies
Add the soaked chilies and salt to the mortar. Use a rhythmic pounding motion until the chilies lose their structure and become a thick, uniform paste.
Add the aromatics
Add the lemongrass and galangal. Pound and twist the pestle until the fibers are completely pulverized and indistinguishable from the chilies.
Incorporate the soft components
Add the shallots, garlic, and lime zest. Pound these into the mixture until they release their juices and blend into a singular, cohesive mass.
Finish with shrimp paste
Add the shrimp paste last and give the mixture a final, thorough pound to ensure it is fully incorporated into the curry base.
Other turns to take.
Green Curry Paste
Swap the dried chilies for fresh green bird's eye chilies and increase the amount of kaffir lime zest.
Massaman Style
Toast coriander seeds, cumin, and cloves in a dry pan before grinding them into the paste mixture.
When it doesn't go to plan.
Keep your non-dominant hand cupped over the mortar opening while pounding to prevent chili bits from flying out.
If the paste feels too thick to process, add the shrimp paste earlier; its moisture helps lubricate the mixture.
Fresh paste is best used immediately, but it can be stored in a sealed jar in the refrigerator for up to one week.
The ones that keep coming up.
Can I substitute ginger for galangal?
You can, though the result will lack the distinct, piney citrus aroma that galangal provides; use half the amount of ginger as it is more pungent.
How do I know the paste is done?
The paste should look like a smooth, thick clay. If you see distinct chunks of lemongrass or chili skin, keep pounding.
