A Mixed Sashimi Platter, known in Japan as Moriawase Sashimi (盛り合わせ刺身), is one of the finest expressions of Japanese cuisine. Rather than relying on complicated cooking techniques, sashimi celebrates the natural flavor, texture, freshness, and beauty of premium seafood. Every slice is carefully cut to highlight each fish's unique characteristics while creating a visually stunning presentation.

Unlike sushi, sashimi contains only fresh raw seafood without rice. A well-prepared mixed platter typically includes several varieties of fish, shellfish, and seafood arranged artistically alongside traditional garnishes such as shredded daikon radish, shiso leaves, wasabi, lemon, and edible flowers.

Whether served at high-end sushi restaurants, traditional ryokans, celebrations, or family gatherings, a mixed sashimi platter symbolizes craftsmanship, freshness, and respect for nature.

Always purchase sushi-grade seafood from reputable suppliers.

Preparing the Seafood

Step 1: Keep Everything Cold

Place seafood over ice while preparing.

Cold temperatures maintain texture and freshness.

Step 2: Clean the Fish

Pat each fillet dry with paper towels.

Remove:

  • Bones
  • Skin (if necessary)
  • Bloodline
  • Membranes

Step 3: Slice Properly

Always cut across the grain.

Slice using one smooth pulling motion.

Never saw back and forth.

Typical thickness:

  • White fish: thin
  • Tuna: medium
  • Salmon: medium-thick
  • Scallops: sliced horizontally
  • Squid: finely scored
  • Octopus: thin slices

Preparing the Garnishes

Shred daikon into fine strands.

Soak in ice water for 10 minutes.

Drain thoroughly.

Wash:

  • Shiso leaves
  • Herbs
  • Flowers
  • Lemon slices

Keep chilled.

Arranging the Platter

Begin by placing shredded daikon as the base.

Arrange fish by:

  • Color contrast
  • Texture
  • Height
  • Balance

Alternate white and red fish.

Place shellfish separately.

Add:

  • Lemon wedges
  • Wasabi
  • Ginger
  • Shiso leaves
  • Edible flowers

Japanese presentation values empty space as much as the ingredients themselves.

Preparing the Dipping Sauce

Mix together:

  • Soy sauce
  • Ponzu

Serve fresh wasabi separately.

Guests can adjust seasoning individually.

How to Eat Mixed Sashimi

  1. White fish
