Thai Toasted Rice Powder (Khao Khua)
This isn't a garnish; it is a structural component of Northeast Thai cooking. When stirred into a dressing, the powder absorbs the lime juice and fish sauce, thickening the liquid and adding a roasted aroma that ties the salad together.
Raw rice is the only way.
Use raw glutinous rice (sticky rice) for the best result, as its high starch content creates a superior crunch. Do not use pre-cooked, jasmine, or basmati rice, as they will turn bitter or mushy.

What goes in.
- 1/2 cupraw glutinous rice
- 2kaffir lime leaves, torn (optional)
- 1dried red chili (optional)
Watch for the deep gold transition
The rice will move from opaque white to pale tan, then suddenly hit a deep, rich golden brown. Remove it from the heat the moment it smells toasted and looks like dark honey; it goes from toasted to burnt in seconds.
The method.
Heat the skillet
Place your skillet over medium-low heat. Do not add oil.
Toast the grains
Add the raw rice to the dry pan. If using lime leaves or chili, add them now. Stir constantly to ensure even browning.
Observe the color
Continue stirring for 7–10 minutes. The grains will pop slightly and turn a deep, dark golden brown. You are looking for an intense, nutty fragrance.
Cool completely
Remove the rice from the pan immediately and spread it on a plate to stop the cooking. If you leave it in the hot pan, it will continue to darken and turn acrid.
Grind the texture
Once fully cooled, transfer to a mortar and pestle. Grind until you have a mix of fine powder and small, crunchy bits. Aim for a coarse, gritty texture rather than a fine flour.
When it doesn't go to plan.
Make a larger batch and store it in an airtight glass jar for up to a month; it loses its potency over time.
If you don't have a mortar and pestle, use a spice grinder, but use short pulses to avoid turning it into a powder that is too fine.
The kaffir lime leaves are optional, but they infuse the rice with a bright citrus oil that complements the heavy nuttiness.
The ones that keep coming up.
Can I use regular jasmine rice?
You can, but the texture will be different. Jasmine rice is harder and doesn't have the same starch profile as glutinous rice, meaning it won't be as crisp or fragrant.
How do I know if I burned it?
If the rice turns dark brown or black and smells acrid rather than nutty, discard it. It will make your entire dish taste bitter.
