Ingredients
1 Spanish mackerel fillet
2 tbsp Sugar
2 tbsp Miso paste
2 tbsp Japanese cooking wine (sake)
2 tbsp Water
3 slices Fresh ginger, thinly sliced
Directions
In a microwave-safe dish, whisk together the sugar, miso paste, sake, and water until well combined. Distribute the sliced ginger evenly across the bottom of the dish.
Score the mackerel fillet along the spine side with a shallow notch. If the fillet is large, cut it in half. Place the fillet on top of the ginger mixture with the skin side facing up. Spoon the miso mixture over the flesh side of the fish.
Cover the dish with microwave-safe plastic wrap and microwave on 500W for 5 minutes, until the fish is cooked through and flakes easily when tested with a fork (internal temperature should reach 145°F).
Carefully remove the plastic wrap and spoon the miso sauce over the fish once more. Serve immediately while hot.
Comments
Spanish mackerel is seasonal and excellent when available at coastal North Carolina suppliers, but sake requires a liquor-store stop and miso paste means a trip to Harris Teeter's international section or an Asian market—not always stocked at all locations. The stated 10 minutes ignores the crucial step of bringing the braising liquid to temperature and reducing it, which adds 8 to 10 minutes; budget 20 minutes total. The dish is straightforward to execute once ingredients are in hand, and the cost per serving stays low if you buy miso in bulk, making it ideal for two diners with access to both a fish counter and specialty aisles, but not a true weeknight grab-and-go.
