My Tuna Tataki is a block of sashimi tuna lightly seared and served with Ponzu Dressing. It is almost like the Tuna Tataki dish at the world-famous chef Nobu’s restaurant.
Prep Time does not include the time required to make Ponzu.
Place the tuna blocks on a cutting board. Salt lightly and sprinkle black pepper over the long sides of the blocks (note 6). Do not put salt and pepper on the two small sides that are perpendicular to the long sides.
Cook until the bottom of the tuna changes colour, about 2-3mm/ 1/8" into the flesh (about 15-20 seconds, note 7).
Remove the tuna blocks to a plate, leave them to cool (note 8). You can put them in the fridge to speed up the cooling process.
Slice the seared tuna into 5-6mm/¼" thick pieces.
Drain and squeeze the daikon to get rid of excess moisture and pile up half of the daikon on the perilla leaf on each plate, topped with a piece of tomato.
Drain and squeeze the daikon to get rid of excess moisture and pile up half of the daikon on each serving plate, slightly off-centred.
Make a vertical incision to the daikon piece, three quarters of the way through so that the bottom part of the daikon is intact.
1. I used two cuboid shaped tuna blocks that are about 3cm x 3cm x 10cm/1¼" x 1¼" x 4" each (Serving Option 1 photo). I also used 3cm x 4cm x 7.5cm/1¼" x 1½" x 3" (Serving Option 2 photo). It does not have to be the same size and the thickness can vary, i.e. when sliced, it does not have to be square.
I recommend that the length be no longer than 15cm/6” as it becomes difficult to handle. The thickness needs to be no less than 3cm otherwise you can’t see much of the red raw meat within the seared trimming.
2. The amount of pepper depends on how spicy you want it to be but do not make it too peppery. See the step-by-step photo as a guide.
3. Please see the Ponzu recipe in my post Japanese Dressings. You can keep Ponzu for many months in the fridge, so I recommend making a good quantity ahead of time. Ponzu is great for Chilled Tofu, Yudōfu and hot pot dishes such as Shabu-shabu.
4. I used a 10cm/4" long piece of daikon to make long strands of daikon salad. Slice the daikon lengthwise very thinly, then pile sheets of daikon slices up in the same direction and slice them very thinly.
5. Momiji oroshi is a spicy grated daikon with chillies. It is called this because the red colour of the daikon resembles the autumn momiji (Japanese maple tree) leaves.
The recipe for Momiji Oroshi makes more than you need for Tuna Tataki. But you can keep Momiji Oroshi in the freezer. It goes very well with Ponzu Dressing.
6. I place two tuna blocks close together on a cutting board and sprinkle salt and pepper. Then turn the block 90 degrees and sprinkle pepper and salt. Repeat to season four long sides of the tuna block.
7. Depending on the temperature of your frying pan, the duration varies. Instead of relying on cooking duration, check the thickness of the seared portion – 2-3mm/ 1/8".
8. Do not slice the seared tuna while warm as it tends to break and become flaky.
