Red Curry Paste (Nam Prik Kaeng Daeng)

Making Thai red curry paste from scratch is the difference between a good curry and a great one. Store-bought paste can’t match the aromatic punch of freshly dry-roasted spices, soaked chilies, and pounded aromatics. This traditional recipe builds the paste one layer at a time.

Dry-roasting the cumin and coriander seeds in a hot pan without oil is the first and most important step. One to two minutes over medium heat transforms raw, flat-tasting seeds into deeply fragrant, toasted spices. You’ll smell the change before you see it. Once they’re lightly browned and aromatic, they’re ready.

Soaking the dried chilies for 10 minutes softens them enough to pound into a smooth paste. Skipping this step leaves you with tough, fibrous bits that never break down. The shrimp paste adds a funky, salty umami that gives the curry its savory backbone.

Chef Tips

• Use a mortar and pestle for the most authentic texture. A food processor works but produces a wetter, less concentrated paste.
• Pound the hardest ingredients first (dried spices, salt) and the softest last (shallots, garlic). This builds the paste gradually.
• Bergamot (kaffir lime) skin adds a floral citrus note that’s distinctly Thai. If you can’t find it, use a small strip of regular lime zest.
• This paste freezes well for up to 3 months. Press into ice cube trays for easy portioning.

Variations

• Use fewer dried chilies for a milder paste, or add fresh Thai bird chilies for extra heat.
• Double the batch and freeze half. Having homemade curry paste on hand makes weeknight curries effortless.
• Pair with coconut milk and chicken, shrimp, or tofu for a classic red curry.
