To prepare this roll, you need the skin of a smoked salmon. Because they live in cold water, salmon build up a particularly delicious thick layer of fat under the skin, making their skin best for this preparation. Purchase smoked salmon with the skin or ask for the skin at your local fishmonger or food store. In many food shops where smoked salmon is cut to order from a large fillet, this delicious skin may simply be thrown away. I cook the skin in a skillet (no oil is added). The layer of fat attached to the skin gradually melts during cooking and makes it crisp.
The pickled mountain burdock—a long, thin, orange-colored root vegetable about 8 inches in length, often packed in a plastic bag containing eight to ten pieces with pickling solution—can be found at Japanese or Asian food stores. If it is not available, use carrot instead.
½ pound skin of smoked salmon
1 package yamagobo no tsukemono (pickled mountain burdock) or 5 ounces julienned carrot, 3 inches long
1 small Kirby cucumber (2 ounces), julienned, 3 inches long
7 half-sheets nori (laver); choose the thicker variety
Put the salmon skin in a skillet, skin side down, and cook over medium-low heat until it is golden and crispy, turning it over once. Remove from the skillet and cut it into ¼-inch-wide strips, 8 inches long. Cut the pickled mountain burdock in half crosswise and then cut each piece in half lengthwise.
