Ingredients

• For the Tuna Sashimi:
• 8-10 ounces (225-280g) sashimi-grade tuna block or loin (yellowfin or bigeye recommended)
• 1 small daikon radish or 1/2 English cucumber, thinly sliced (optional garnish)
• 2 scallions, thinly sliced (optional garnish)
• 2 tablespoons pickled ginger (gari), store-bought (optional garnish)
• 1 teaspoon toasted sesame seeds (optional garnish)
• For the Quick Ponzu (Dipping Sauce):
• 3 tablespoons low-sodium soy sauce (or tamari for gluten-free)
• 1 tablespoon fresh citrus juice (from lime or lemon; yuzu juice is a fantastic, authentic swap if you can find it)
• 1 tablespoon rice vinegar (unseasoned)
• 1 teaspoon mirin (Japanese sweet rice wine) or a small pinch of granulated sugar (about 1/4 teaspoon)
• Optional: 1/2 teaspoon freshly grated ginger or 1/4 teaspoon toasted sesame oil (use sparingly to avoid overpowering the tuna)
• For Serving:
• 1-2 teaspoons wasabi paste, store-bought

Directions

1. Chill & Set Up Your Station (5 minutes)
   1. Place a clean serving plate or platter in the refrigerator to chill. Keeping everything cold is key to excellent sashimi.
   2. Carefully unwrap your tuna block. Using paper towels, gently pat the entire surface of the tuna very dry. This helps with clean slicing and prevents excess moisture.
   3. Set up your cutting board. Keep a damp cloth or a few paper towels nearby to wipe your knife blade clean between slices.
   4. Remember: you'll slice the tuna right before serving to maintain its freshness and texture.
2. Make the Quick Ponzu (2 minutes)
   1. In a small bowl or jar, combine the soy sauce, citrus juice, rice vinegar, and mirin (or sugar).
   2. Whisk vigorously or shake well until all ingredients are fully combined.
   3. Taste the ponzu. If you prefer it tangier, add a bit more citrus. If you want it a little saltier, add a tiny splash more soy sauce.
   4. If using, stir in the optional grated ginger or toasted sesame oil. Set aside.
3. Slice the Tuna the Right Way (5-8 minutes)
   1. Place your dried tuna block on the cutting board. Look closely at the tuna to identify the "grain" – these are the muscle fibers that run through the fish. For sashimi, you want to slice across the grain. This makes the fish more tender to eat.
   2. Using a very sharp, long slicing knife (like a yanagiba or a long chef's knife), position the blade at a slight angle (around 30-45 degrees) to the tuna block.
   3. Starting from the heel of the blade, make one long, smooth, pull-slice motion towards yourself, slicing completely through the tuna. Avoid a sawing motion, as this can tear the delicate fish.
   4. Aim for a consistent thickness of about 1/4 inch (approximately 0.6 cm).
   5. Wipe your knife blade clean with a damp cloth or paper towel after every one or two slices to prevent tuna residue from building up and affecting your cuts.
   6. Continue slicing until all the tuna is prepared.
4. Plate Like a Sushi Bar (2 minutes)
   1. Retrieve your chilled plate from the refrigerator.
   2. Arrange the tuna slices artfully on the plate. A common technique is to fan them out slightly or arrange them in a neat row.
   3. If using, arrange the daikon or cucumber slices, scallions, pickled ginger, and a sprinkle of toasted sesame seeds around the sashimi.
   4. Serve immediately with the quick ponzu dipping sauce on the side and a small dollop of store-bought wasabi. Enjoy your homemade fresh fish and seafood delight!
