Gently poach the chicken in the coconut milk, fish sauce, sugar and lime leaves until just cooked (about 10 minutes depending on size). Leave the chicken to cool in the liquid. Once cool, shred by hand.

Crush the chillies in a mortar and pestle, then add the sugar and combine until you have a wet paste.

Add remaining ingredients and pound (you can use a food processor but the mortar and pestle gives a better result). Adjust to taste. If the dressing is too hot add more coconut liquid.

For the salad: Place the rice in a wok over high heat and stir until the rice turns opaque and lightly toasted. When cool, crush into fine crumbs in a spice grinder or mortar and pestle. Place the clean wok over high heat with the peanut oil. When the oil is hot, add the dried chillies and move about with a ladle. They will turn dark brown very quickly. Turn onto kitchen paper. When cool, crush to a powder as for the rice.

Combine the papaya, chicken, lime leaves, herbs and dressing. Place on serving plates and sprinkle with the ground rice and blackened chilli.
