- Prepare the toppings: Slice the tuna and salmon very thinly on the bias, with pieces about 2 inches long. Slice the cucumber in half and again in half length wise. Using a mandolin on a very thin setting, slice the cucumbers into spears, lengthwise. Cut them into 2 inch pieces. Slice the radishes on the mandolin.
- To make the donuts: Working around the donut mold in batches, press the fish into the bottom of the donut mold, then the cucumbers, then the radishes, then spoon in the salmon roe, and sprinkle in the sesame seeds. Repeat with each mold. You can mix up the order! Finally, press in the rice on top of the other ingredients, making the top of the rice as flat as possible. Place the mold in the refrigerator for at least 5 minutes. Remove from the refrigerator and place a flat plate or tray on top of the mold and flip over the mold. Carefully remove the mold from the donuts making sure that none of the ingredients are still inside the mold. Top the donuts with slices of chives and serve with soy sauce or Ponzu sauce, pickled ginger, and wasabi paste.
- To make perfect sushi rice: Thoroughly rinse 1½ cups of sushi rice (short-grain) until water is clear and not muddy. Place in a rice cooker, along with 2 cups water. Cook until button pops up and light changes to “warm.”
- Meanwhile, in a small sauce pot, combine 3 tablespoons rice vinegar, 2 tablespoons sugar, and 1 teaspoon salt. Dissolve over medium heat but do not boil. Remove from heat and stir. Set aside to cool. Once rice is finished, let sit in the steamer for 5 minutes. Remove rice and place into a wooden, or non-reactive bowl. Using a wooden or plastic paddle, gently fold in the vinegar mixture until well combined. Do not squish the grains! Let rice cool to room temperature before handling.
