Step-by-Step Instructions
Step 1. Prepare the Mackerel and Aromatics
- Sprinkle salt on both sides of the mackerel fillets and let them rest for 15 minutes to draw out excess moisture and reduce fishy smell.
- slice green onions into 1-inch chunks and thinly slice a thumb-sized piece of fresh ginger.
- Blanch the mackerel in hot water (around 173°F/80°C) for about 10 seconds to tighten the surface and remove impurities. Rinse with cold water and pat dry.



Step 2. Simmer the Mackerel in Broth
- In a pot, combine water, cooking sake, and sugar. Bring to a boil.
- Add the mackerel to the boiling broth and simmer over high heat.
- Add sliced ginger and chopped green onions.
- Place a piece of parchment paper or aluminum foil over the pot as a drop lid to ensure even cooking. Simmer on medium heat for about 5 minutes.




Step 3. Incorporate the Miso Paste
- Dissolve white miso paste with a bit of broth, then gently stir it into the pot in two stages, simmering for 3 minutes after each addition.
- Add soy sauce and continue simmering for another 5 minutes to deepen the flavor and color.
- Add the remaining miso and simmer for a final 3 minutes, allowing the liquid to reduce and the flavors to concentrate.



Step 4. Finish and Serve
- Once the sauce is thick, turn off the heat and serve.
