How to make Black Cod Fillets Poached in Five-Spice Broth with Baby Bok Choy and Udon
Back to contentsPat the fillets dry and sprinkle all over with salt and pepper.
In a small bowl, whisk together the chicken broth, sherry, soy sauce, sugar, five-spice powder, and sesame oil. Set aside.
Heat a 12-in/30.5-cm skillet with a lid over medium-high heat and add the vegetable oil. When the oil shimmers, add the bok choy stems, carrot, and ginger and sauté until the bok choy turns bright green and the ginger is fragrant, about 2 minutes. Add the broth mixture and bring to a simmer. Add the noodles and give them a stir to keep them from sticking. When the broth returns to a simmer, top the noodles and veggies with the fish, bok choy leaves, and spring onion. Cover, reduce the heat to low, and simmer until the noodles and fish are tender and cooked through, about 4 minutes. Taste and add more soy sauce or pepper if the mix needs it.
Divide the noodles and fish between two warmed shallow bowls and ladle the broth and vegetables over. Garnish with the coriander and sesame seeds and serve hot.
