Kao kua is a normal base additive to Thai sauces. Also called “rice powder” or “jasmine powder”, it’s essentially pulverized dry-fried rice.
Basically put 3x (three times) as much rice grains (I prefer jasmine)Â as you need powder in a fry pan with no water or oil or anything, cook them over medium-high heat, tossing frequently, until browned (but before smoke detectors go off). Let cool a little, grind into nothingness with a mortar and pestle (or freezer bag and heavy thing like rolling pin).
Total cook time ~3-5 minutes.
Serves no one. It’s an additive.
