Poach the Chicken: Add chicken to a large pot with ginger, scallions, turmeric, and salt. Cover with cold water. Bring slowly to a gentle simmer. Cook 35-40 minutes, skimming impurities for a clean broth. Check doneness by piercing the thickest part - juices should run clear. Remove chicken and let cool. Reserve broth.
Render the Chicken Fat: Place chicken fat trimmings in a cold pan. Render over medium-low heat until liquid and golden. Remove solids and reserve fat.
Toast & Cook the Rice: Wash rice thoroughly. Heat rendered chicken fat gently and sauté garlic. Add rice and toast until grains turn slightly opaque. Transfer to rice cooker. Add exactly 3 parts reserved broth (2 parts glutinous: 1 part jasmine). Stir in turmeric for color. Cook until fluffy.
Optional Chicken "Glow-Up": Mix turmeric with oil and lightly brush over chicken skin for color only. This step is purely aesthetic.
Tear the Chicken: Once cooled, hand-tear chicken along the grain into bite-sized pieces. Do not slice - tearing gives better texture.
Make the Herb Salad: Combine onion, herbs, scallions, and cilantro. Season with bouillon, black pepper, lime juice, fish sauce, and fried shallots. Mix with hands. Taste and adjust.
Serve: Fluff rice and plate with chicken, pickled carrots and daikon, cucumber slices and herb salad. Serve at room temperature. Finish with extra fish sauce and lime if desired.
