Homemade Thai Spice Blend Recipe
Toasting the whole seeds before grinding wakes up their essential oils, and drying out the lemongrass and kaffir lime leaf concentrates their citrus perfume so the blend stays potent for months instead of fading like fresh aromatics do within days.

Instructions
- 1Set a dry skillet over medium-low heat. Add the coriander seeds, cumin seeds, and white peppercorns and toast, shaking the pan often, for 3-4 minutes until fragrant and a shade darker. Remove from the heat immediately and let cool completely.
- 2Transfer the toasted seeds to a spice grinder or mortar and pestle along with the dried galangal, dried lemongrass, and dried kaffir lime leaf. Grind to a fine, even powder.
- 3Add the dried chile flakes, garlic powder, shallot powder, turmeric, and salt to the ground mixture and pulse or grind again until fully combined and no large flecks remain.
- 4Sift the blend through a fine-mesh strainer, regrinding any coarse bits left behind, so the final powder is uniform.
- 5Store in an airtight jar away from light and heat.
Tips & variations
- If dried galangal or kaffir lime leaf aren't available, they can be found at most Asian grocery stores in the dried spice or herb section, don't substitute fresh versions since the added moisture will clump the powder.
- For a hotter blend, double the dried chile flakes or add a pinch of ground white chile.
- Rub this blend directly onto chicken or pork before grilling, or stir a spoonful into coconut milk as the base for a quick curry sauce.
- A small handful of dried shrimp powder, ground in with the other spices, adds a savory depth closer to traditional Thai curry pastes.
Storage & reheating
Store the finished spice blend in an airtight jar in a cool, dark cabinet for up to 6 months. Keeping it away from the stove's heat and light preserves the aroma much longer than storing it on an open spice rack. Whole toasted seeds ground fresh right before use will always taste stronger than a blend that has sat for months, so label the jar with the date it was made.
Tips from the Tulo kitchen
- Grinding the toasted seeds while they're still slightly warm makes them easier to pulverize into a fine powder than letting them cool completely first.
- A coffee grinder dedicated to spices works faster than a mortar and pestle and produces a more consistent texture for this blend.
FAQ
What is in a Thai spice blend?
A typical blend combines toasted coriander and cumin seeds with white pepper, dried galangal, lemongrass, kaffir lime leaf, chile, garlic, and shallot, the same aromatics found in Thai curry pastes but in dried, shelf-stable form.
Can I use this blend instead of curry paste?
It works well as a dry rub or a stir-fry seasoning, but it won't replace wet curry paste in soups like tom kha or green curry, since those rely on fresh chile and fish sauce for body and heat.
Is Thai spice blend the same as Chinese five-spice?
No. Five-spice leans on star anise, cinnamon, and cloves for a sweet-warm profile, while this blend is built around citrusy lemongrass and kaffir lime leaf with a sharper, more herbal edge.
How long does homemade spice blend stay fresh?
Ground spice blends lose potency faster than whole spices; use this one within 6 months for the best aroma, and store it away from the stove's heat and steam.
