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 - Once cooked through, transfer the chicken immediately to an ice bath to stop the cooking process and firm up the skin. Set aside to cool completely.
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. Add rinsed jasmine rice and stir to coat evenly.
07 - 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 chilies, garlic, ginger, lime juice, sugar, salt, and chicken broth in a blender. Process until smooth and bright red. Adjust seasoning to taste.
09 - Whisk together light soy sauce, sesame oil, chicken broth, and sugar in a small bowl. Stir until sugar completely dissolves.
10 - Chop the cooled chicken into bite-sized serving pieces, working through joints for clean cuts.
11 - Arrange chicken pieces over a bed of fragrant rice. Garnish with sliced cucumber and fresh cilantro sprigs. Serve alongside chili sauce, soy dipping sauce, and a bowl of hot chicken broth.
