Use flounder, fluke, sole, sea or striped bass to make this unusually attractive and delicious appetizer. Save some kelp from stock making (covered in plastic wrap it will keep in the refrigerator for 3–4 days) and the next time you’re in the fish market ask for a small piece of the freshest fillet they have. Make up a fish roll—it will keep quite nicely for 4–5 days—and slice off a few pieces at a time.
If you have a broad piece of kelp left over from stock making, that is perfect. Place it in a pot with a quart of cold water. Bring the water to a boil rapidly, then remove the pot from the heat. Let the kelp sit in the broth until it is cool enough to handle. (Save this broth and use it in lieu of regular dashi stock in other recipes.) If you are using a dried piece of kelp, let it cook for 2 minutes before removing the pot from the heat.
Lay the fish fillet on a flat dish and lightly salt all surfaces. Put the fish aside for 10–15 minutes and you’ll notice a bit of liquid has accumulated. Pat this away gently with paper towels. Cut the fillet in half, lengthwise, slightly on the diagonal. Now lay the two pieces side by side in a small, shallow dish and pour in enough rice vinegar to cover the pieces entirely. Let the fish marinate for at least 30 minutes, but not more than 1 hour, at room temperature.
In the meantime, cut the lemon peel into the thinnest possible slivers. Or peel the ginger and slice it as thin as you can. Pile these slices up, then cut them into very thin threads.
Lift the fish from the rice vinegar, reserving the vinegar for later. Place the fish on a cutting board and, using the sharpest knife you have, cut very thin slices on the diagonal. The outer surfaces of the fish will have already turned opaque from contact with the vinegar; the inner surfaces may still be translucent. Move the slices to a corner of your board and wipe your cutting surface dry before laying down the broad ribbon of kelp. Now arrange the slices of fish on the kelp, leaving a
Just before serving, lift the roll or rolls from the marinade. Insert decorative toothpicks evenly spaced about
