Sashimi Omakase Platter

Ensure your cutting board, sashimi knife, and hands are impeccably clean. Prepare a bowl of ice water for chilling fish. Gently pat all sashimi-grade fish fillets dry with paper towels. Keep fish chilled in the refrigerator or on ice until ready to slice.

Peel the daikon radish and slice it into very thin rounds, then julienne these rounds into fine strands (tsuma). Arrange the daikon tsuma in a small bowl of ice water to keep it crisp. Wash shiso leaves and pat them dry. Prepare fresh wasabi if using a grater, or portion out prepared wasabi and pickled ginger.

Place the tuna fillet on your cutting board. Using a long, sharp sashimi knife, slice the tuna against the grain in a single, fluid motion. Aim for slices approximately 1/4 inch thick. For Akami, rectangular slices are common; for Chutoro, slightly thicker slices can be appealing. Arrange slices neatly on a chilled plate or ice.

Repeat the slicing technique for the salmon and yellowtail fillets. For salmon, consider slicing at a slight angle to create wider, elegant pieces. Yellowtail often benefits from slightly thicker slices to highlight its rich texture. Keep all sliced fish chilled and separated.

If using large scallops, slice them horizontally into 2-3 thin rounds. For other optional seafood like octopus or sweet shrimp, prepare them according to their specific requirements, ensuring they are clean and ready for consumption. Briefly chill all prepared seafood.

Arrange the sliced sashimi artfully on a large, chilled serving platter or individual plates. Vary the placement of different fish types and colors for visual appeal. Place small mounds of daikon tsuma, shiso leaves, and pickled ginger strategically. Add small dollops of wasabi near the fish, or in a separate dish. Garnish with lemon wedges.

Serve the Sashimi Omakase Platter immediately with high-quality soy sauce in small dipping bowls. Encourage guests to enjoy each piece with a small amount of wasabi and a dab of soy sauce, using pickled ginger to cleanse their palate between different types of fish. Enjoy the fresh flavors and textures.
