01 - Rub the chicken all over with salt to exfoliate the skin, then rinse thoroughly under cold water.
02 - Fill a large stockpot with enough water to submerge the chicken. Add ginger slices and scallion pieces. Bring to a rolling boil over high heat.
03 - Carefully lower the chicken into the boiling water. Reduce heat to a gentle simmer. Cover and poach for 40 to 50 minutes, skimming off any foam that rises to the surface.
04 - Transfer the cooked chicken to an ice bath immediately to stop the cooking process and firm up the skin. Let cool completely, then set aside.
05 - Strain the poaching liquid through a fine mesh sieve. Reserve the clear broth for cooking rice and as a soup base.
06 - Heat chicken fat or vegetable oil in a saucepan over medium heat. Sauté minced garlic and ginger until fragrant, about 1 to 2 minutes.
07 - Add rinsed jasmine rice to the pan, stirring to coat evenly with the aromatics. Pour in 3 cups of reserved chicken broth and salt. Bring to a boil, then reduce heat to low, cover, and cook for 15 to 18 minutes until rice is fluffy and liquid is absorbed.
08 - Combine red chilies, garlic, ginger, lime juice, sugar, salt, and chicken broth in a blender. Process until smooth and well combined.
09 - Whisk together light soy sauce, sesame oil, chicken broth, and sugar in a small bowl until sugar completely dissolves.
10 - Chop the cooled chicken into bite-sized serving pieces using a sharp knife and cleaver.
11 - Arrange chicken pieces over a bed of fragrant rice. Garnish with fresh cucumber slices and cilantro sprigs. Serve with chili sauce, soy dipping sauce, and a bowl of hot chicken broth on the side.
