Cube the tuna and vegetables except for the coriander. Remove the seeds from the tomatoes and cucumber.
Marinate the tuna in its flavoring ingredients, and the vegetables in their flavoring ingredients. Chill in the refrigerator.
Put a round plating mold on a plate. Press the tuna in the mold with a spoon, then top with the vegetables.
Take the mold off, add the fresh coriander leaves and the vegetable marinade, and it's done.
It's also nice with shrimp and nanohana. Sprinkle with lemon juice to taste.
I used an empty can with both ends removed as my circular mold. See photo.
Second from the left is the white wine vinegar I used.
Story Behind this Recipe
I created an Italian style maguro (lean tuna) recipe for a special occasion.
I removed the seeds from the vegetables for a prettier finish. Arrange on plates just before serving.
