Pulverize aromatics. In a food processor, add the shallots, garlic, and ginger and pulverize until it finely chopped. Divide 1/2 for the marinade and 1/2 for the curry. Set aside.
Marinate the chicken. Cut the chicken into 2-3 inch pieces. Place the chicken in a large mixing bowl and add 1/2 of the aromatics, salt, chicken powder, sugar, vegetable oil, paprika, and rice cooking wine. Mix all together and cover to marinate for at least 3-4 hours or preferably overnight.
Pan fry the vegetables. In a large skillet, heat enough oil to cover the bottom of the pan over medium high heat. Once the oil is hot, work in batches to lightly pan fry the potatoes, taro and carrot until lightly browned on each side. Set aside on a paper towel lined baking tray.
Pan-fry the chicken. In a large skillet, heat about 3 tablespoons of oil over medium-high heat. Once the oil is hot, work in batches to lightly fry the chicken about 30 seconds on each side until golden brown. Set aside.
Saute the aromatics. In a large pot, add 4 tablespoons of vegetable oil over medium heat. Then add the lemongrass and cook for about 2 minutes. Then add the remaining 1/2 of the reserved aromatics toss to combine and cook until fragrant and golden brown.
Add spices. Lower the heat to low and add the curry powder, turmeric powder, five-spice, and bay leaves. Mix to combine for 30 seconds.
Add chicken and coconut water. Add back the chicken and toss to combine. Then add the coconut water, salt, chicken bouillon powder, and sugar. Cover the pot, increase the heat to medium-high heat, and bring to a boil. Then reduce to medium-low heat and gently simmer for 20 minutes.
Add milk, coconut milk, and vegetables. After 20 minutes, add the milk, coconut milk, potatoes, taro, carrots and onion. Cover and simmer for 15 minutes. Add 1 tablespoon of fish sauce to taste. Season to taste with extra sugar, fish sauce, or salt. Remove the lemongrass and bay leaves.
Serve. Garnish with cilantro and green onions and serve with a slice of French baguette. Enjoy!
