Aromatic bases & spice pastes
Phanaeng (Panang) curry paste
น้ำพริกแกงพะแนง · A fragrant, mildly spicy Thai aromatic paste from the red curry paste family, distinguished by toasted coriander and cumin seeds plus ground peanuts. It serves as the foundational flavor base from which the rich, coconut-cream-based panang curry is built, and is reusable across many Thai savory dishes.
The formula
2 parts fresh aromatics : 1 part dried chilies : 1/2 part roasted peanuts
Proportions are guidelines; shrimp paste and salt are used as small accents (~1–2 tsp per batch).
Identity
- Deep red-orange hue from dried red chilies
- Thick, slightly grainy paste with visible peanut flecks
- Bright aroma of lemongrass and makrut lime layered over toasted cumin
- Background note of roasted nuts and savory shrimp paste
- Mild to moderate heat despite the saturated red color
- Clings to a spoon without separating or weeping liquid
Ingredients
| Flavor | Dried red chilies, soaked | Mild varieties such as guajillo or puya are typical; traditional Thai chilies or árbol can be added for more heat. |
| Aromatics | Lemongrass, galangal, makrut lime zest, garlic, shallot, coriander root | Sliced thinly for pounding; only the tender inner bulb of lemongrass is used. |
| Flavor | Toasted coriander seed | Dry-toasted until fragrant — supplies the warm, citrusy depth characteristic of panang. |
| Flavor | Toasted cumin seed | Dry-toasted until fragrant — the defining spice that sets panang apart from generic red curry paste. |
| Flavor | Shrimp paste (kapi) | Traditional umami base; toasted briefly first to mellow its pungency. Omitted in vegetarian adaptations. |
| Seasoning | Coarse sea salt | Coarse grains act as an abrasive when pounding by hand; fine salt works if using a food processor or blender. |
| Flavor | Roasted unsalted peanuts | Distinctive to panang — gives nutty flavor and full-bodied, slightly thick texture. |
| Aromatics | Fresh turmeric root | Optional in some modern recipes for deeper color and earthy undertone. |
Method
- 1Soak dried chilies in warm water 15–20 minutes; meanwhile dry-toast coriander and cumin seeds in a pan until fragrant.Rehydrates the chilies for clean grinding; toasting releases the volatile oils in the seeds that give panang its signature warmth.
- 2Slice lemongrass, galangal, garlic, shallot, makrut lime zest, and coriander root as thinly and evenly as possible.Thinner slices break down more completely under the pestle, reducing grit and shortening pounding time.
- 3Pound ingredients in small batches in a mortar, starting with salt and the hardest aromatics, then chilies and toasted seeds, and finishing with peanuts and shrimp paste.Layering by hardness ensures each element is fully pulverized before the next is added, producing a smooth, balanced paste rather than a coarse slurry.
- 4Combine the pounded components in the mortar and work together with the pestle until homogeneous and cohesive.Even amalgamation guarantees uniform flavor release when the paste is later bloomed in fat.
- 5Taste, adjust salt, and pack into a clean glass jar, capping with a thin layer of neutral oil if storing.The oil seal prevents oxidation and prolongs shelf life of refrigerated paste.
Techniques that matter
Dry-toasting seeds
Unlocks aromatic oils and adds the warm, earthy notes central to panang's identity versus plain red curry paste.
Layered pounding in a mortar and pestle
Pulverizing each ingredient fully before combining produces a smoother texture and clearer, brighter flavors than bulk grinding all at once.
Frying the paste (khaw phrik gaeng)
Cooking the paste in coconut cream or oil triggers Maillard reactions, transforming raw pungency into the round, nutty depth expected in a finished panang curry.
Variations & derivatives
Vegetarian / vegan panang pasteWestern adaptation
Shrimp paste is omitted; a small amount of miso or extra salt plus a splash of soy sauce compensates for lost umami.
Spicier southern-style panang pasteSouthern Thailand / Thai–Malaysian border regions
Uses a higher proportion of small hot Thai dried chilies for more aggressive heat.

Used in these dishes
Substitutions
- Galangal → Fresh young ginger — Ginger is sharper and more peppery; close cousin but not identical.changes result
- Shrimp paste (kapi) → Miso paste or fish sauce — Miso supplies both umami and salinity; fish sauce adds savoriness only and may need extra salt.
- Makrut (kaffir) lime zest → Regular lime zest — Lacks the floral, citrus-oil intensity of makrut; acceptable in a pinch.
- Dried Thai red chilies → Guajillo or puya chilies — Milder and smokier; easily available outside Thailand. Mix in Thai or árbol chilies to restore heat.
- Roasted peanuts → Roasted cashews — Give similar richness and fat content; cashew flavor is sweeter and less earthy.
- Coriander root → Coriander stems (plus extra ground seed) — Stems retain some fresh earthy note; ground seed alone loses the raw-root character.changes result
Troubleshooting
Finished curry tastes raw or harsh
Paste was not bloomed long enough in fat before liquids were added → Fry the paste in 2–3 Tbsp coconut cream or oil over medium heat 3–5 minutes until it darkens and smells nutty.
Curry has fibrous bits or gritty texture
Hard aromatics (lemongrass core, galangal fibers) were not pounded finely enough → Pound in smaller batches, slice thinner, or finish with a food processor; strain fibrous bits if necessary.
Paste lacks depth and tastes one-dimensional
Spices were not toasted, or shrimp paste was skipped without compensation → Re-toast cumin and coriander until just fragrant; add a small pinch of miso or a splash of fish sauce.
Paste turns bitter during cooking
Seeds or peanuts were over-toasted/burnt before grinding → Discard and start over, toasting only until fragrant and removing from heat immediately.
