Saba no Misoni

Saba no misoni is Japanese home cooking at its best: rich mackerel fillets simmered gently in a sweet, savory miso sauce with ginger. The fish turns silky, the sauce turns glossy, and a bowl of steamed rice is all you need beside it.

Ingredients
- 4 mackerel fillets (about 500 g)
- 3 tablespoons miso paste
- 2 tablespoons mirin
- 1 tablespoon sake
- 1 tablespoon sugar
- 1 tablespoon soy sauce
- 1 piece ginger (about 30 g), sliced
- 200 ml water
- 2 spring onions, sliced
- Steamed rice, to serve
Instructions
- Score the skin of each mackerel fillet with two shallow cuts and pour boiling water over them, then pat dry.
- Whisk the miso, mirin, sake, sugar, soy sauce, and water in a shallow pan until smooth.
- Add the ginger and bring the sauce to a gentle simmer.
- Lay the fillets skin-side up in the sauce, cover with a lid, and simmer for 12 minutes.
- Remove the lid and spoon the sauce over the fish for 2 minutes until glossy.
- Serve with the sauce spooned over, scattered with spring onions and steamed rice.
Pro tips
- The boiling-water rinse removes the fishy smell and firms the skin.
- Keep the simmer gentle — a hard boil will break the fillets apart.
- Do not overcook; mackerel turns dry quickly once it passes done.
Frequently asked questions
Can I use another fish?
Yes. Salmon, sardines, or yellowtail all work in the same miso sauce. Adjust the simmering time to the thickness of the fillet.
Which miso is best?
A red or awase miso gives the deepest flavor. White miso works too but makes a milder, sweeter sauce.
Can I make this ahead?
It is best fresh, but leftovers keep in the fridge for a day. Reheat gently in the sauce so the fish stays moist.
