Step 1Mix together the tamarind paste and the water, then press it through a sieve; it'll be like a paste. Combine it with the chicken and let it stand for 2 minutes.
Step 2Heat a medium skillet over high heat and add the oil. Add the garlic and shallots and cook until the shallots start to become translucent, about 30 seconds. Add the chicken to the pan; stir until it's cooked through, about 3 to 5 minutes.
Step 3Transfer the chicken, garlic and shallots to a large bowl. Stir in the fish sauce, lime juice, sugar and pepper flakes. Add the mint leaves, red onion and Roasted Rice Powder and toss to mix. Divide the chicken mixture among 6 plates. Arrange the green onions, cucumber and carrot slices along with the cabbage wedges around each plate and serve.
Step 1Toast the rice in a dry skillet over medium-low heat. Keep stirring as the rice cooks. Once the rice is light brown and fragrant, transfer it to a blender or food processor. Blend the rice until it's rough and the grains are about 1/4 their original size. Set aside.
