Step 1

Heat the oil in a wok or large saucepan over medium-low heat. Cook the lemon grass, garlic and ginger for 1 minute or until aromatic. Stir in the curry powder, sweet potato and carrot. Add the coconut milk, stock and bay leaves. Simmer for 25 minutes or until the vegetables are almost cooked.

Step 2

Add the chicken to the wok. Cook, stirring occasionally, for 7 minutes or until the chicken is cooked through. Stir in the sugar and fish sauce. Season with pepper. Transfer to a serving bowl and top with coriander.
