Ingredients
Step-by-Step Instructions
Step 1. Prepare the Ingredients
- Choose a thick radish, peel it, and cut it into thick (2-3cm) half-moon slices. Set aside the radish skin.
- Cut the white part of the long green onion into thin strips and soak in water to remove the tangles.
- cut some into rings and some into thin strips.
- Wash the yellowtail fillets thoroughly under running water, then pour very hot boiling water over them until the surface turns white. Immediately pour out the water and cool the fillets in cold water.




- Clean the yellowtail fillets further, removing any remaining scales or slime, being gentle to avoid tearing the flesh.

Step 2. Simmer the Radish and Yellowtail
- In a frying pan or pot, arrange the radish slices and skins. Add sake and water, bring to a boil, then reduce heat and simmer.
- Add the yellowtail fillets to the pot, along with the ginger rings and lightly crushed green onion. Add sugar to remove the fishy odor and enhance sweetness.
- Simmer until the yellowtail is cooked through and the radish is tender. Remove any impurities that rise to the surface.



Step 3. Reduce the Sauce and Finish
- Remove the radish and yellowtail; add soy sauce to the cooking broth and let it reduce, removing the lid for the last part of cooking.
- Add a little rainbow sauce halfway through the reduction process. Once the sauce has reduced, add the radish and yellowtail back to the pot.


Step 4. Serve and Garnish
- Serve the yellowtail and radish, garnished with white onion strips and ginger strips. Add mustard to taste.
