Full Recipe:

Ingredients

For the Seared Tuna Tataki

  • Tuna block (sashimi-grade): about 8 oz (225 g)
  • Cooking oil: 1-2 tbsp for searing
  • Shiso leaves or green onions: for topping
  • Sesame seeds: for garnish (optional)

For the Wasabi Ponzu Sauce

  • Soy sauce: 2 tbsp
  • Lemon juice: 1 tbsp (freshly squeezed)
  • Wasabi paste: 1/2 tsp (adjust to taste)

Steps to Make It

Step 1: Prepare the Shiso Leaves or Green Onions

  1. If using shiso leaves, thinly slice them. Shiso leaves are aromatic and pair wonderfully with fish. If they are unavailable, thinly slice green onions as a flavorful substitute.
  2. Set aside these garnishes to use later.

Step 2: Sear the Tuna

  1. Heat a small amount of cooking oil (about 1-2 tbsp) in a frying pan over medium-high heat. Let it heat until it shimmers.
  2. Gently place the tuna block in the pan. Sear each side of the tuna for approximately 15-20 seconds. Rotate the tuna to ensure all sides, including the top and bottom, are seared evenly. The goal is to cook only the outer layer while keeping the center raw and tender.
  3. Once seared, immediately transfer the tuna block to a cutting board. This step stops it from cooking further and preserves the rare center.

Step 3: Slice the Tuna

  1. Using a sharp knife, trim off the ends of the tuna block.
  2. Slice the tuna into 1/4 inch (6 mm) thick pieces.
  3. Arrange the sliced tuna on a serving plate, slightly overlapping each piece.
  4. For optimal taste and texture, place the sliced tuna in the refrigerator for 30 minutes to 1 hour to chill before serving.

Step 4: Make the Wasabi Ponzu Sauce

  1. In a small bowl, combine the soy sauce, lemon juice, and wasabi paste.
  2. Whisk well until the wasabi is fully dissolved and the sauce is smooth.
  3. Adjust the flavor by adding more wasabi or lemon juice if desired.

Step 5: Assemble and Serve

  1. Pour the Wasabi Ponzu sauce over the sliced tuna, allowing the flavors to enhance the taste of the fish.
  2. Garnish with thinly sliced shiso leaves or green onions and a sprinkle of sesame seeds.
  3. Serve this delicate and refreshing tuna tataki as an appetizer or as part of a larger Japanese meal.

Frequently Asked Questions (FAQs)

1. Can I use frozen tuna for this recipe?
Yes, as long as it’s sashimi-grade. Let it thaw completely in the refrigerator before searing. Sashimi-grade tuna is flash-frozen to eliminate potential parasites and is safe for consumption when raw.

2. What can I serve with Tuna Tataki?
Tuna Tataki is great served with a side of white rice or as part of a Japanese-themed meal with miso soup, pickled vegetables, and edamame.

3. Can I substitute shiso leaves?
If shiso leaves are unavailable, green onions or even cilantro can work as flavorful garnishes. Shiso leaves offer a unique, minty flavor, but green onions provide a fresh touch that complements the tuna well.

4. Is there a substitute for wasabi paste?
If you can’t find wasabi paste, you can use a small amount of horseradish, which has a similar kick. Adjust the quantity based on your taste.

5. Can I make this dish ahead of time?
Yes, you can prepare it a few hours in advance. Keep the seared tuna and the Wasabi Ponzu sauce refrigerated separately, and assemble them just before serving to maintain freshness.

Tips for Perfect Results

  • Use Sashimi-Grade Tuna: For the best texture and safety, always choose sashimi-grade tuna, as this ensures it is safe for raw consumption.
  • Keep the Tuna Cold Before Searing: Cold tuna will sear quickly without cooking the center, giving you a nicely browned exterior and a rare center.
  • Control the Heat Carefully: Medium-high heat is perfect for searing the tuna quickly, creating a golden crust without overcooking. Be sure to rotate the tuna swiftly.
  • Slice with a Sharp Knife: For clean, even slices, use a sharp knife. Slicing the tuna smoothly will enhance the presentation.
  • Chill Before Serving: Chilling the seared tuna for 30 minutes to an hour helps the texture set and enhances the flavors when paired with the Ponzu sauce.

Storage Tips

  • Refrigerate Leftovers: Store any leftover tuna tataki in an airtight container in the refrigerator for up to 1 day. However, it is best enjoyed fresh.
  • Wasabi Ponzu Sauce: The sauce can be prepared ahead and stored in a sealed container in the fridge for up to 3 days.
  • Avoid Freezing: Freezing may alter the texture of the tuna once seared and sliced, so it’s best to avoid freezing this dish.
