Spanish Mackerel in Japanese Sesame Sauce

The scent of toasted sesame still instantly transports me back to a tiny Tokyo eatery, tucked away in a vibrant backstreet. Rain was drumming on the awning outside as I slurped down perfectly cooked mackerel, its delicate flavor amplified by a rich, nutty sesame sauce. The warmth of the meal, the cozy atmosphere, and the genuine hospitality – it was a moment of pure culinary bliss that I’ve tried to recapture in my own kitchen ever since. This recipe is my homage to that memory, a simple yet satisfying dish that brings a touch of Tokyo to your table.

• Cook Time: 4 minutes
• Resting Time: 1-2 minutes
• Total Time: 15 minutes
• Servings: 2
• Dietary Type: Pescatarian

Ingredients

• 150 g Spanish mackerel fillet (sawara)
• 1 pinch salt
• 1 pinch pepper
• 1/4 yellow onion
• 2 cabbage leaves
• 50 g shimeji mushrooms
• 50 g eringi mushrooms
• 2 tablespoons sake
• 1 tablespoon ponzu sauce
• 1 tablespoon sesame oil
• 1 tablespoon mirin
• 1/2 tablespoon vinegar
• 2 tablespoons sesame paste (neri goma)
• 1 tablespoon miso
• 1 teaspoon sugar
• 1/2 teaspoon sesame seeds

Equipment Needed

• Microwave-safe dish
• Parchment paper
• Small bowl
• Knife
• Cutting board

Instructions

1. Begin by preparing the Spanish mackerel. Season the fish fillets generously with salt and pepper on both sides. This simple step is crucial for enhancing the natural flavor of the fish.

2. Now, prepare the vegetables. Remove the hard center part of the cabbage and slice the leaves into thin shreds. Thinly slice the yellow onion. Remove the root part of the shimeji mushrooms and separate them into individual pieces. Slice the eringi mushrooms lengthwise into several pieces. Varying the size and shape of the vegetables will add visual appeal and textural interest to the final dish.

3. Prepare the flavorful sesame sauce. In a small bowl, combine the sake, ponzu sauce, sesame oil, mirin, vinegar, sesame paste (neri goma), miso, sugar, and sesame seeds. Mix well until all the ingredients are thoroughly combined and the sauce is smooth. If you can’t find neri goma, you can substitute it with tahini sauce. The miso adds a deep umami flavor, while the ponzu provides a citrusy tang.

4. Cut out a piece of parchment paper approximately 30cm x 30cm. Place the parchment paper on top of a microwave-safe dish. This will create a convenient cooking pouch.

5. Arrange half of the cabbage, onion, and mushrooms on one side of the parchment paper. Place one piece of the seasoned Spanish mackerel fillet on top of the vegetables. Repeat this process with the remaining half of the vegetables and the other fillet.

6. Carefully wrap the parchment paper to enclose the fish and vegetables completely, creating a sealed pouch. This will help to steam the ingredients evenly and retain moisture.

7. Cook the pouch in the microwave for 4 minutes using a power level of 600W. The cooking time may vary depending on your microwave, so it’s important to monitor the fish for doneness. Cook the second batch of fish and vegetables in the same manner.

8. After the microwave has stopped, keep the parchment paper closed for an additional 1-2 minutes. This allows the residual steam to continue cooking the fish and vegetables, ensuring they are perfectly cooked through.

9. Gently open the parchment paper pouch, being careful to avoid the escaping steam. Pour the prepared sesame sauce generously over the fish and vegetables.

10. Serve immediately and enjoy the harmonious blend of flavors.

Expert Tips & Tricks

• For a deeper sesame flavor, lightly toast the sesame seeds in a dry pan before adding them to the sauce. This will bring out their natural aroma and nuttiness.
• To prevent the fish from overcooking in the microwave, ensure that the parchment paper pouch is tightly sealed. This will trap the steam and cook the fish evenly.
• If you prefer a richer sauce, you can add a small amount of Japanese mayonnaise to the sesame mixture.
• Feel free to experiment with other vegetables, such as bok choy, snow peas, or carrots. Adjust the cooking time accordingly.
• For a spicier kick, add a pinch of red pepper flakes to the sesame sauce.
• If you don’t have a microwave, you can cook the fish and vegetables in a steamer basket over boiling water. Steam for approximately 8-10 minutes, or until the fish is cooked through.

Serving & Storage Suggestions

Serve the Spanish mackerel in Japanese sesame sauce immediately while it’s hot and flavorful. The dish pairs perfectly with a side of steamed rice or quinoa to soak up the delicious sauce. Garnish with extra sesame seeds and a sprig of fresh cilantro or scallions for an added touch of freshness.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. When reheating, it’s best to gently warm the fish in a pan over low heat or in the microwave. Avoid overheating, as this can dry out the fish.

This dish is not recommended for freezing, as the texture of the fish and vegetables may change upon thawing.

Variations & Substitutions

• For a gluten-free version, ensure that the ponzu sauce and miso are gluten-free. Tamari can be used as a substitute for soy sauce in some ponzu recipes.
• If you don’t have Spanish mackerel, you can substitute it with other firm-fleshed fish such as salmon, cod, or sea bass.
• For a vegetarian option, replace the fish with tofu or tempeh. Marinate the tofu or tempeh in a mixture of sake, soy sauce, and ginger before cooking.
• Experiment with different types of mushrooms, such as shiitake, maitake, or oyster mushrooms.
• Add a touch of heat by incorporating gochujang (Korean chili paste) or sriracha into the sesame sauce.
• For a richer flavor, use roasted sesame oil instead of regular sesame oil.
