Fish
Finishing & Serving
Method
Preparation for Dry-aging
- 1
Inspect and Dry
Rinse the madai briefly under cold water to remove any loose scales or blood, then pat completely dry inside and out with paper towels. Any surface moisture will prevent proper drying and could inhibit aging.
- 2
Set up aging bed
Line a shallow, nonreactive tray (ceramic, glass, stainless steel) with the rice bran or kosher salt to form an even bed about 1–1.5 cm thick. This bed helps absorb moisture and support the fish, promoting even airflow.
- 3
Salt the fish
Lightly and evenly rub the exterior of the fish with a thin layer of the coarse sea salt. Focus on the skin and the cavity, but do not pack it with salt. The goal is controlled dehydration and mild curing — not heavily salting the flesh.
- 4
Position the fish
Place the salted madai on the prepared bed, belly down, with some space around it for airflow. If you have a wire rack, set the fish on the rack over the bed so air can circulate on all sides; otherwise place directly on the bed.
Dry-aging
- 5
Refrigerate for aging
Move the tray with the fish to the coldest part of your refrigerator, ideally at 1–3°C (34–38°F). Leave the door closed as much as possible to keep temperature stable.
- 6
Age duration
Age the madai for 2–5 days depending on desired intensity. For subtle concentration, 2 days; for more pronounced umami and firmer texture, 4–5 days. Check daily for any off-odors or spoilage — it should smell clean, briny, and slightly nutty.
- 7
Turn and re-bed (optional)
If aging more than 2 days, gently turn the fish once after 48 hours to promote even drying and redistribution of moisture. Replace any saturated rice bran or salt under the fish if needed.
Finishing
- 8
Remove salt and rinse
After the chosen aging time, remove the fish from the refrigerator. Brush off or gently rinse away the surface salt and rice bran under cold running water if needed. Pat completely dry with paper towels.
- 9
Fillet or portion
Using a very sharp filleting knife, remove the head if desired, then fillet the madai into two clean sides or make thin sashimi slices, depending on intended service. Dry-aged madai will be firmer and easier to slice thinly; aim for uniform slices 2–4 mm for sashimi or larger portions for grilling.

Optional quick sear (alternate serving)
For a warm preparation, pat dry fillets, season very lightly with salt, and sear skin-side down in a hot skillet with 1 tsp oil for 1–2 minutes until skin is crisp; finish in the oven for 2–3 minutes at 180°C if fillets are thick. Rest 1–2 minutes, then slice and serve with the same garnishes.
