Japanese Flounder Recipe

Flounder: A mild, white fish that is perfect for absorbing the flavors of the sauce.

Soy sauce: A salty, umami-rich sauce made from fermented soybeans, essential in Japanese cuisine.

Mirin: A sweet rice wine that adds a delicate sweetness to the dish.

Sake: A Japanese rice wine that enhances the overall flavor profile.

Sugar: Adds a touch of sweetness to balance the savory elements.

Vegetable oil: Used for cooking the fish, providing a neutral flavor.

When cooking flounder, ensure the pan is adequately heated before adding the fish. This helps to achieve a nice, golden-brown sear on the fillets. Additionally, when pouring the sauce mixture over the fish, tilt the pan slightly to allow the sauce to coat the fillets evenly, enhancing the flavor and ensuring the sauce thickens properly.

• Allow the flounder fillets to cool completely before storing. This prevents condensation, which can lead to sogginess and spoilage.
• Transfer the cooled fillets to an airtight container. If stacking, place a piece of parchment paper between each fillet to avoid sticking.
• Store the container in the refrigerator if you plan to consume the flounder within 2-3 days. Ensure the temperature is consistently below 40°F (4°C).
• For longer storage, wrap each fillet tightly in plastic wrap, then place them in a freezer-safe bag. Squeeze out as much air as possible to prevent freezer burn.
• Label the bag with the date of freezing. Properly stored, the flounder can last up to 3 months in the freezer.
• When ready to reheat, thaw the flounder in the refrigerator overnight. Avoid thawing at room temperature to prevent bacterial growth.
• Reheat the flounder gently in a pan over low heat, adding a splash of water or vegetable oil to maintain moisture. Alternatively, reheat in the microwave on a low setting, covered with a microwave-safe lid to retain moisture.
• Serve the reheated flounder with freshly steamed rice and a side of vegetables for a quick and delicious meal.
