Method
- Pour boiling water over the mackerel fillets in a colander for ten seconds — the skin will tighten. This sets the flesh and removes the surface fishiness. Pat dry.
- Combine water, sake and sliced ginger in a wide pan. Bring to a gentle simmer over medium heat. Lay the fillets in skin-up; the liquid should come halfway up the fish.
- Cover with a drop-lid (a piece of parchment cut to size, with a centre hole, lying directly on the fish) — this keeps the fillets submerged without circulation breaking them up. Simmer five minutes.
- Whisk both misos with sugar, mirin and soy in a small bowl until smooth. Ladle 4 tablespoons of the hot poaching liquid into the bowl, whisk, then return the slurry to the pan. Never dump miso directly into a hot pan — it scorches.
- Re-cover with the drop-lid. Simmer ten more minutes, basting the fish with sauce every two minutes by tipping the pan. The sauce should reduce to a glossy syrupy glaze; the flesh should turn from pearl-pink to opaque white.
- Lift each fillet onto a plate. Spoon the glaze over generously. Top with julienned ginger and spring onion. Serve with hot short-grain rice and a small dish of pickles — never with bread, which masks the dish.

Cultural Note
Saba no misoni is everyday Japanese home cooking — saba (mackerel) is the cheapest oily fish in the market, and miso turns its strong flavour into virtue. Almost every Japanese household has its own ratio of red to white miso for this dish; in northern Japan the red dominates, in Kyoto the white. The drop-lid (otoshibuta) is one of those quiet Japanese cooking innovations — it does what neither a pot lid nor uncovered cooking can.
