First, prepare the toasted rice powder.
Place the jasmine rice in a dry pan over medium heat.
Cook while stirring the rice constantly, until the grains turn lightly golden.
Remove the grains from the heat, and let them cool down.
Once cooled, grind the toasted rice in a mortar and pestle or in a spice grinder until they reach a coarse powdery consistency.
Set the toasted and ground rice aside for later.
Heat a large pan over medium heat, and add the vegetable oil.
Add the ground chicken, along with the salt.
Cook the ground chicken, stirring and breaking it up into small pieces, until the chicken is fully cooked and no longer pink.
Once the ground chicken is fully cooked, remove from the heat and place in a large bowl.
While the chicken is cooling down, prepare the dressing.
In a small bowl, combine the fish sauce, lime juice, soy sauce, and palm sugar.
Stir until the sugar is fully dissolved.
Add the toasted rice powder to the bowl with the cooked ground chicken.
Add the sliced spring onions, chopped bird’s eye chili, and the prepared dressing that you made earlier with the fish sauce, lime juice, soy sauce, and palm sugar.
Toss well to combine all of the ingredients and coat the chicken in the dressing.
Lastly, fold in the fresh mint, cilantro, and Thai basil leaves.
The herbs should be bountiful here, and play a central role in the dish, rather than just a tiny garnish at the end.
To serve, spoon generous amounts of the Larb Gai onto the separated lettuce or cabbage leaves.
Top with a bit of extra Sambal Oelek on top, and a drop or two of extra fish sauce and lime juice, if desired.
