Nitsuke-Style Round Scad

---

You don’t need a professional Japanese pantry to enjoy a good nitsuke. Because my time and local grocery options are often limited, I love finding ways to bring those iconic Japanese flavors to the ingredients I already have. This Nitsuke-Style Round Scad is a perfect example: it’s a simple and deeply flavorful fusion that proves you can make a gourmet-inspired meal even on a tight schedule.

If you are wondering about the choice of fish, round scad is actually galunggong. Growing up in a Filipino household, this was always the reliable, everyday fish on our table, usually fried to a crisp and served with rice. But I wanted to see if I could take this humble staple and turn it into something a bit more refined. By applying the Japanese simmering technique, the meaty texture of the fish completely transforms. It is a beautiful way to honor a local favorite while giving it a savory-sweet, special feel that is surprisingly easy to achieve in any home kitchen.

What is Nitsuke?

In Japanese cuisine, Nitsuke refers to a traditional method of simmering fish in a savory-sweet poaching liquid. The base is almost always a combination of soy sauce, mirin, sake, sugar, and plenty of ginger to balance the natural oils of the fish. It’s a technique designed to keep the fish incredibly moist and tender while coating it in a glossy, umami-rich glaze.

My Twist on the Tradition

While a traditional Japanese nitsuke often starts by poaching the raw fish directly in the liquid, my version takes a slight detour. I’ve found that with a heartier fish like galunggong, a quick pan-sear before simmering makes a world of difference.

Here is why I prefer this modern approach:

• Better texture. Searing the fish first creates a light crust that prevents the skin from breaking apart during the simmer.
• Deals with the “fishy” aroma. Since I don’t always have access to the freshest catch of the day or every traditional Japanese deodorizing ingredient, searing helps mellow out the stronger flavors of the scad.
• Depth of flavor. Sautéing the garlic and onions before adding the liquid creates a savory base that pairs perfectly with the sweet soy glaze.

It might not be the strictly traditional way you’d find in a high-end Tokyo kitchen, but for a busy home cook, it’s a more reliable way to get a delicious, restaurant-quality result every single time.

Why You’ll Love This Recipe

This dish started as an experiment in my kitchen, a way to see if I could combine a Japanese classic with a familiar local favorite. Here is why I think this recipe works so well:

• A new way to cook a favorite. It is a sophisticated way to prepare scad or galunggong. If you usually only have it fried, this simmering technique shows how versatile this fish can be.
• Pantry-friendly. You don’t need a specialty grocery store. It uses basic items like soy sauce, ginger, and sugar to get those Japanese flavors.
• One-pan process. Since we sear and simmer in the same pan, cleanup is fast. It is a simple way to make a meal that looks and tastes refined.
• Balanced flavors. The heat from the ginger and the saltiness of the soy create a balanced sauce that goes perfectly with a bowl of rice.
• Accessible ingredients. This recipe proves you don’t need expensive ingredients to make something special. It is all about using a simple technique to make affordable fish taste great.

Ingredients for Nitsuke-Style Round Scad

Round scad (galunggong). This is the heart of the dish. Its meaty, firm texture holds up well to simmering without falling apart. If you can’t find round scad, mackerel or even small tilapia will work; you just want something firm enough to handle being flipped in the pan.

Ginger. It adds a warm heat and helps balance the natural oils of the scad. For this recipe, I used my leftover homemade gari (Japanese pickled ginger) because I didn’t have fresh ginger on hand, and it worked surprisingly well. If you are in the same situation, don’t hesitate to use it.

Garlic and onion. These aromatics are sautéed at the start to create a savory, fragrant base that adds depth to the sauce.

Soy sauce. The foundation of the glaze. It provides the deep, salty umami flavor that characterizes the nitsuke style.

Mirin. This Japanese rice wine adds a mild sweetness and is the secret to getting that beautiful, glossy shine on the fish. If you don’t have mirin, use a splash of any white wine you have with an extra teaspoon of sugar. Even a little bit of water mixed with honey works if you need that sweet, glossy finish.

Water. Used to dilute the sauce so the flavors are balanced and the fish has enough liquid to simmer in without becoming too salty.

Brown sugar. I used brown sugar for the color, but white sugar or honey works just as well. Honey actually makes the sauce a bit thicker and shinier.

Cooking oil. A small amount is needed to sear the fish and sauté the aromatics at the start.

Green onions. Chopped and added at the very end for a fresh bite and a pop of color against the dark sauce.

How to Make Nitsuke-Style Round Scad

1. Prep and dry the fish. Clean the round scad (galunggong) and pat them completely dry with paper towels. This is a non-negotiable step to ensure a proper sear rather than steaming the fish.
2. Sear for texture. Heat cooking oil in a pan over medium-high heat. Sear the fish on both sides until the skin is lightly golden; this helps it stay firm during the simmering process. Remove the fish and set it aside.
3. Sauté the aromatics. In the same pan, sauté the garlic and onion until fragrant and softened to build a savory base.
4. Add the ginger. Stir in the ginger to release its warm heat and balance the natural oils of the fish.
5. Build the simmering liquid. Pour in the soy sauce, mirin, water, and brown sugar. Stir to dissolve the sugar and bring the mixture to a gentle bubble.
6. Simmer and glaze. Return the seared fish to the pan. Simmer on medium-low, occasionally spooning the liquid over the fish until the sauce reduces into a thick, glossy, and syrupy glaze.
7. Final garnish. Transfer to a plate and top with chopped green onions for a fresh bite and a pop of color.

What to Serve with Nitsuke-Style Round Scad

For my first batch, I served this with red rice and a side of sauerkraut. The earthy, nutty flavor of the red rice and the sharp, fermented crunch of the sauerkraut were exactly what was needed to balance the sweet and salty glaze.

If you don’t have those on hand, here are a few other ideas that would work just as well:

• Steamed rice. A classic choice for soaking up the extra soy-mirin sauce.
• Blanched greens. Quick-cooked bok choy or gai lan adds a fresh, crisp texture.
• Miso soup. A simple, light broth to round out the meal.
• Cucumber salad. Sliced cucumbers in vinegar provide a bright, clean bite.
• Steamed corn. The natural sweetness is a great match for the savory glaze.

Meal Prep and Storage

Make ahead. You can clean and dry the fish a few hours in advance. Keep them wrapped in paper towels in the fridge so they stay bone dry until you are ready to sear.

Leftovers. This dish holds up well. The fish continues to soak up the ginger-soy glaze overnight, which makes it even more flavorful the next day.

How to store. Keep the fish in an airtight container. Make sure to pour all that extra glaze over them to keep the meat moist. It stays fresh in the fridge for up to 2 days.

Reheating. Avoid the microwave if possible because it can make the fish rubbery. Instead, put the fish and glaze in a small pan with a splash of water over low heat until the sauce thins out and the fish is warmed through.

Variations and Add-ins

If you want to experiment or make this a more “complete” one-pan meal, here are a few simple ways to change it up:

Add some greens. In the last two minutes of simmering, toss in some baby bok choy, spinach, or even pechay. They will wilt down and soak up that savory-sweet glaze beautifully.

Make it spicy. If you like heat, add a few slices of bird’s eye chili (siling labuyo) when you are sautéing the garlic and ginger. The spice cuts through the richness of the soy sauce perfectly.

Tofu. If you have a block of firm tofu, cut it into cubes and sear them along with the fish. The tofu acts like a sponge for the sauce.

Citrus finish. A tiny squeeze of calamansi or lime right before serving can brighten the whole dish if you find the glaze a bit too heavy or sweet.
