Ingredients
- 400 g sushi rice
- 8 raw sweet shrimp
- 100 g fresh sea urchin
- 200 g sashimi-grade salmon
- 1 avocado
- 4 okra pods
- 2 egg yolks
- to taste shredded nori seaweed
- to taste wasabi
- to taste soy sauce
- to taste lemon wedges
Instructions
- 1Prep the sweet shrimp

Using a small knife or spoon, gently pry the frozen raw sweet shrimp out of the wholesale box. Be careful to do this gently so you do not break the delicate shrimp.
Tip: Keep the remaining shrimp in the box, wrapped tightly in plastic wrap to maintain freshness, and return them immediately to the freezer. - 2Thaw the shrimp

Place the pried-out sweet shrimp into a bowl or onto a plate. Pour mineral water over them to thaw the shrimp gently.
Tip: Using mineral water for thawing helps maintain the clean, sweet flavor of the raw shrimp. - 3Clean the sea urchin

Gently rinse the raw sea urchin under running water. Use scissors to carefully trim and clean away any unwanted parts to reveal the fresh uni inside.
Tip: Handle the sea urchin gently to avoid damaging the delicate uni segments inside. - 4Separate the egg yolks

Crack two eggs and carefully separate the yolks from the whites. Place the yolks into small individual dishes to prepare them for the donburi.
Tip: Make sure no egg white remains with the yolk for a cleaner presentation and richer flavor. - 5Prepare the okra

Blanch the okra in boiling water for one minute. Remove, drain, and then chop the blanched okra into small, neat pieces on a cutting board.
Tip: Blanching ensures the okra stays vibrant in color and removes any raw, grassy texture. - 6Prepare the avocado

Slice the avocado in half and remove the pit. Use a spoon to scoop the avocado flesh cleanly out of the skin, then slice it into neat, uniform pieces.
Tip: Choose a ripe avocado that is firm but yields slightly to pressure for the best texture in your donburi. - 7Slice the avocado

Take the avocado halves and slice the flesh into neat, even pieces. These slices will form the creamy base of your donburi toppings.
Tip: Keep your knife slightly angled for more aesthetically pleasing avocado fans. - 8Peel the sweet shrimp

Carefully peel the shells off the thawed raw sweet shrimp. It is essential to keep both the head and the tail attached to ensure a beautiful presentation when served.
Tip: Use a small knife to help lift the shell segments if they are difficult to remove. - 9Slice the salmon

Using a sharp knife, slice the fresh salmon fillets into thin, uniform strips. Consistent sizing ensures that each bite of your donburi is balanced.
Tip: Slice against the grain for the most tender texture. - 10Assemble the donburi

Start building your donburi by layering the prepared ingredients over a bed of rice. Arrange the chopped okra, avocado slices, salmon strips, and peeled sweet shrimp attractively in the bowl.
Tip: Place the heavier items first to provide a stable base for the more delicate garnishes. - 11Add the sea urchin

Gently place portions of the fresh sea urchin onto the assembled rice bowl using a spoon. Be very delicate, as sea urchin is soft and can easily break apart.
Tip: Position the sea urchin near the center for a premium focal point.
