.You can't really go wrong with ponzu sauce, and this turned out great. While the preparation took a lot longer than I expected, the actual cooking portion was quick and easy, as with most seared dishes. I seared the steak on the BBQ at high heat, and let it cook for 5-7 additional minutes on medium heat, lid closed. I especially had fun with the presentation of this dish. I used a few pieces from my sushi set, and easily made the best looking dish of my life. Next time I may try some spices and pepper on the meat, and add lemon wedges to the serving plate. In the end it tastes great, looks great, and would be a good way of introducing someone to Japanese style cooking.
This was wonderful. We had a "Japanese" themed evening and this was our appetizer. My only change was that I didn't follow the cooking directions. I put the sirloin on a broiler pan in the oven at 500 degrees for 15 minutes exactly. I brought it out, let it sit and then sliced thinly. I remived the onions from the Ponzu sauce and served seperately so we could dip the Tataki in the sauce. The onions by themselves were delicious.
