Steamed fish needn't be boring: Here salmon fillets and blanched cabbage are rolled in cabbage leaves. The little packages are steamed, then served over mellow rice noodles with a tangy soy, sesame, and rice-wine vinegar sauce.
Bring a large saucepan of water to a boil. Peel off 6 of the big outer leaves, without holes, from each cabbage; set aside. Core and thinly slice the cabbages. Fill a medium bowl with ice and water; set aside. Blanch the cabbage leaves in boiling water until bright green and flexible, about 1 minute; plunge into the ice bath. Drain on paper towels. Blanch the remaining sliced cabbage until just tender, about 1 minute. Drain the cabbage; immerse in the ice bath. When cool, drain in a colander; set aside.
In a small bowl, combine the chicken stock, honey, vinegar, ginger, garlic, soy sauce, and sesame oil; set aside. Bring a saucepan of water to a boil. Cook the rice noodles until tender, about 3 minutes. Transfer the noodles to a colander; rinse under cold water to stop the cooking. Drain well; transfer to a bowl. Toss with 1/3 cup of the soy mixture; set aside.
Bring a wok or large skillet of water to a simmer. Season each salmon fillet with salt and pepper. Carefully cut out the stiff stems of the reserved cabbage leaves. Place 2 leaves on a work surface, slightly overlapping. Place a fillet on each leaf. Top with about 1/2 cup sliced cabbage, and roll leaves "burrito" style. Divide the remaining sliced cabbage among the bottom of each level of the bamboo steamer. Place the salmon packages seam side down on the cabbage. Cover the steamer; place in the wok or skillet. Steam until the salmon is just cooked through, 15 to 18 minutes. For the sauce, add the scallions to the remaining soy mixture. Serve the salmon packages and steamed cabbage over the noodles with the sauce.
You will need a two-level bamboo steamer for this recipe.
