Like bacon and eggs, kamo (duck) and negi (leek) can be listed as just two ingredients on a menu, but the combination is so well known in Japan that people can envisage the dish based only on those two words alone. Kamo negi is usually seared, thinly sliced duck breast accompanied by the whites of leeks that have been slowly pan-fried or roasted to have nicely brown grill marks. It could be served plated
as an okazu (side dish) as part of a larger feast, or made into a delightful noodle soup. I’ve included both versions of the dish here, as you can double the amount of duck breast and turn it into two completely different meals. It is best to start this recipe the day before, to allow the duck breast to cure with the salt and sansho overnight. This draws out water from the meat while seasoning the duck at the same time, resulting in crispier duck skin and more flavoursome meat.
2 duck breasts
2 teaspoons salt
1 teaspoon ground sansho pepper
1 thin leek, cleaned, whites cut into 4 pieces, greens discarded or used for stock
30 ml (1 fl oz) soy sauce
30 ml (1 fl oz) sake
15 g (1/2 oz) zarame or sugar
1 bunch of spring onions
500 ml (2 cups) dashi (see page 32 of book for recipe)
250 g (9 oz) ramen noodles, home-made (see page 130 of book for recipe) or store bought
1 bunch of green vegetables, washed and cut into bite-sized pieces
shichimi togarashi, to serve
Using a sharp knife, remove any silver skin from the underside of the duck breasts. Rub 1 teaspoon salt over the skin and meat of each breast, then rub the sansho pepper over only the flesh. (We season only the meat side with the sansho, because the sansho will burn on the skin side, which is pan-fried for a longer time than the meat side.) Place the duck breasts, skin side up, on a rack with a tray underneath. Leave uncovered in the refrigerator for up to 24 hours, but at least 2 hours.
When ready to cook, use a sharp knife to cut lines down the duck skin, along the length of the breast, about 2 mm (1/8 inch) deep and 1 cm (1/2 inch) apart. This creates channels for the duck fat to render out, resulting in a crispier skin.
Place the duck, skin side down, in a cold frying pan and turn the heat to medium–low. When the duck starts sizzling and a thin layer of rendered duck fat coats the bottom of the pan, add the leek to the pan.
Cook for 15 minutes over medium–low heat, skin side down the whole time; there should be a light frying noise. Every 5 minutes, drain the fat from the pan, reserving it for roasted potatoes or stir-fries. Turn the leek over after 7 minutes.
Meanwhile, in a small saucepan, heat the soy sauce, sake and zarame just enough to dissolve the zarame. At this point, you can take the recipe in two different directions.
FOR THE PLATED VERSION:
Wash the spring onions, then divide into the green and white parts. Shred the green bits and very thinly julienne the whites, keeping them separate.
After the duck has finished cooking on the skin side for 15 minutes, turn it over onto the flesh side and sear all the parts that appear uncooked. After you’ve seared each side, leave the duck on the meat side for a further minute (it should be 2 minutes in total), then transfer the duck and leek from the pan to a plate and allow to rest for 5 minutes. Take the pan off the heat, but do not wash.
After 5 minutes, place the pan back on the heat and turn the heat up to high. Add the spring onion greens and stir-fry until wilted. Add the soy sauce mixture and any accumulated juices under the duck. Allow to bubble until slightly thickened, then remove from the heat. Slice the duck, then place on your serving dish with the leek. Pour the sauce over, garnish with the spring onion whites and serve.
FOR THE SOUP VERSION:
While the duck is cooking, bring the dashi to a simmer and prepare a pot of boiling water for cooking the noodles.
After the duck has finished cooking on the skin side for 15 minutes, very quickly sear the flesh side of the duck just to colour it, then remove from the pan with the leek. Don’t worry if you think it’s still raw; it will cook further in the soup.
Quickly blanch your vegetables in the boiling water; remove with tongs and place in a colander to drain. Boil the noodles in the same water, then pour into the colander to drain, shaking the colander to remove as much excess water as possible.
Divide the noodles and vegetables among bowls. Add 3 tablespoons of the soy sauce mixture to the simmering dashi. Taste and add more of the dashi mixture, or salt, until you are happy with the flavour. Pour it over the noodles and top with the greens. Slice the duck breast and fan it out over the noodles with the leek. Serve with shichimi togarashi for sprinkling over.
