Steamed Fish Collar (Kama) Japanese Izakaya Style

The first time I encountered a perfectly steamed fish collar was in a small izakaya in Tokyo, not in some fancy restaurant, but in a crowded, no-frills bar where the salty aroma of ginger and soy drifted from the kitchen. One bite and I understood why this cut is revered by Japanese cooks. The tender, buttery meat practically melts on your tongue, enriched by natural collagen that renders into silky gelatin.

Fish collars (kama) are the shoulder area of the fish, and they’re nothing short of magic when steamed. Unlike leaner fillets, collars have enough fat and connective tissue to stay moist and deeply flavorful. What surprises most home cooks is how simple it is to prepare, just 15 minutes of gentle steaming, a handful of quality ingredients, and you’ve got restaurant-caliber seafood that tastes like it took hours.

This is exactly the kind of dish that changed how I cook: honest, respectful to the ingredient, and proof that the best seafood doesn’t need complexity. Let’s dive into how to make it yourself.

Why Fish Collars Are Worth Your Time

Fish collars (kama) are the prized shoulder cut that connects the head to the body, it’s where chefs go first. This area is packed with connective tissue and fat, which means intense umami flavor and a texture that’s impossibly silky when cooked gently.

Most home cooks never discover them because they’re not sold as individual fillets, but once you taste a perfectly steamed collar, you’ll understand why Japanese cooks treasure them.

Steaming is the ideal cooking method for this cut because it preserves the delicate texture and allows the natural oils and collagen to render into something luxurious. There’s no high heat scorching the surface, no dry results, just moist, tender fish that tastes like the ocean itself. The izakaya philosophy embraces this simplicity: quality ingredients, minimal manipulation, maximum flavor.

Beyond taste, fish collars deliver serious nutritional benefits. They’re rich in omega-3 fatty acids that support heart health and reduce inflammation. The collagen content isn’t just delicious, it’s genuinely good for your joints, skin, and gut health. This is real food that nourishes your body while tasting absolutely incredible.

Did You Know? A single serving of fish collar provides nearly 25% of your daily omega-3 requirements, making it one of the healthiest seafood choices you can prepare at home.

Choosing the Right Fish Collar

The quality of your finished dish depends entirely on sourcing fresh, high-quality fish collars. Here’s what you need to know to make the right choice.

Best Fish Varieties for This Recipe:

The ideal collars come from fatty, flavorful fish like salmon, yellowtail (hamachi), sea bream (madai), or even mackerel. Salmon collars are the most accessible and forgiving, they have enough fat to stay moist even if steaming goes a minute or two over.

Yellowtail offers a more delicate, refined flavor that’s absolutely stunning. Sea bream delivers that authentic izakaya experience with its subtle sweetness and silky texture.

How to Source Fresh Fish Collars:

Visit a reputable fishmonger or Japanese market rather than relying on standard grocery store fish counters. Ask specifically for “fish collars” or use the Japanese term “kama”, this signals you know what you’re looking for and helps the fishmonger provide exactly what you need.

Look for collars that smell like the ocean, not fishy. The flesh should be firm, moist, and vibrant in color with no browning at the edges.

Fresh vs. Frozen:

Always choose fresh over frozen for this dish. Steaming doesn’t mask texture issues the way other cooking methods do, so you need pristine fish. If fresh isn’t available, frozen collars work in a pinch, just thaw them overnight in the refrigerator, pat dry thoroughly, and proceed with the recipe.

Sizing and Portions:

Plan for 2 to 3 collars per person, depending on size. Most collars weigh between 4 to 6 ounces each. If your fishmonger has larger collars, one per person might be enough. Always ask them to estimate the weight so you can plan portions accurately.

Fast Fact: Fish collars contain up to three times more collagen than fillets, which is why they have that signature silky mouthfeel and are particularly prized in Japanese cuisine.

Ingredients You’ll Need

These simple, quality ingredients are all you need to create an authentic izakaya-style steamed fish collar.

• 2 to 3 fresh fish collars per person (4-6 oz each, salmon or yellowtail preferred)
• 3 thin slices fresh ginger (about 1 inch long), julienned
• 2 green onions (scallions), white and light green parts separated from dark green
• 3 tablespoons soy sauce (shoyu)
• 2 tablespoons sake (or dry white wine as substitute)
• 1 tablespoon mirin (sweet rice wine) or honey
• 1 cup dashi stock (or kombu broth, or water if unavailable)
• Sea salt and white pepper to taste
• Optional: yuzu juice or fresh lemon juice for finishing
• Optional: sesame oil (toasted) for drizzling
• Optional: shichimi togarashi (seven-spice blend) for garnish

The foundation of this dish is the steaming liquid, soy, sake, mirin, and dashi create that perfect balance of savory, slightly sweet, and umami-rich flavors. If you can’t find dashi or mirin, don’t skip the dish. Kombu broth works beautifully, and honey can substitute for mirin. The fish collar is the star; everything else is supporting cast.

Pro Tip: Prep all your ingredients before you start steaming. This is a quick-cooking dish, and you won’t have time to slice ginger or measure soy sauce once the collars hit the heat.

Step-by-Step Instructions

Follow these simple steps to create perfectly steamed fish collars that rival your favorite izakaya.

Step 1: Prepare the Fish Collars

Pat your fish collars completely dry with paper towels. This helps them cook evenly and prevents excess moisture during steaming.

Season each collar lightly with a pinch of sea salt and white pepper on both sides. Let them sit for about 10 minutes, this allows the salt to penetrate the flesh and help it retain moisture during cooking.

Step 2: Build Your Steaming Liquid

In a small bowl, combine the soy sauce, sake, mirin, and dashi stock. Stir until the mirin dissolves completely.

Pour about half of this mixture into the bottom of your steaming vessel (a bamboo steamer, metal steamer basket, or even a covered pot with a steaming rack). You want enough liquid to create steam without the collars sitting directly in broth.

Step 3: Arrange the Collars

Place the seasoned fish collars skin-side down on the steaming surface, leaving space between each one so steam can circulate freely.

Distribute the ginger slices and the white/light green parts of the scallions evenly over the collars.

Step 4: Steam with Precision

Pour the remaining steaming liquid gently over the collars. Cover your steamer tightly.

Bring the steaming vessel to a simmer over medium-high heat. Once you see steady steam, reduce heat to medium and steam for 10 to 12 minutes. The timing depends on the size of your collars, a 5-ounce collar typically needs 10 minutes, while a larger 6-ounce piece might need 12.

Step 5: Check for Doneness

The fish is ready when the flesh turns opaque and flakes gently with a fork. Here’s the key: there should be a slight jiggle to the meat, especially near the bone. Overcooked fish becomes dry and loses that luxurious texture that makes collars special.

If you have a thermometer, the thickest part of the collar should reach 145°F internally. But honestly, visual and texture cues work just as well.

Step 6: Finish with Fresh Elements

Carefully transfer the steamed collars to a serving bowl or plate. Pour some of the steaming broth over them.

Top with the reserved dark green scallion parts, scattered fresh. If using yuzu or lemon juice, squeeze just a small amount over each collar for brightness. A light drizzle of toasted sesame oil adds incredible depth.

If you’re feeling adventurous, add a tiny pinch of shichimi togarashi for a subtle spice note.

Pro Technique: The collagen in fish collars gels as they cool slightly. Serve them warm but not piping hot, this allows you to experience the full silky texture. Give them 2 to 3 minutes to rest after steaming.

Did You Know? Steaming is the gentlest cooking method for fish because there’s no direct heat source. This preserves up to 95% of the nutrients and moisture in the collar, compared to pan-searing which can lose more through evaporation.

Serving & Flavor Finishing Touches

The beauty of steamed fish collars lies in how their natural richness pairs with bright, fresh flavors.

Serve your collars in a shallow bowl with some of the steaming broth pooling around them. The broth is liquid gold, it’s infused with fish umami and should be enjoyed alongside each bite. If you prefer less broth, that’s fine too. Some Japanese cooks enjoy collars with minimal liquid, letting the fish itself shine.

Pairing Suggestions:

Steamed fish collars are authentically served as an izakaya appetizer with cold sake or a crisp beer. If you’re making them as a main course, serve alongside steamed white rice and a simple side vegetable like bok choy or sautéed spinach. A light cucumber salad (sunomono) cuts through the richness beautifully.

Why Finishing Touches Matter:

The yuzu or lemon juice adds acidity that balances the fish’s natural richness. The sesame oil contributes nutty depth. The bright green scallions provide textural contrast and freshness. Together, these elements transform a good dish into an unforgettable one, it’s the difference between good cooking and thoughtful cooking.

Fast Fact: Japanese cooks traditionally serve fish collars with sudachi (a small, tart citrus fruit) or yuzu. If neither is available, fresh lemon juice works beautifully and maintains that same bright acidity.

Storage & Make-Ahead Tips

Leftover steamed fish collars keep well in the refrigerator for up to 2 days when stored properly.

Transfer any leftovers to an airtight container along with the steaming broth. The broth helps keep the collars moist and prevents them from drying out in the fridge. Store at 32 to 40°F in the coldest part of your refrigerator, away from raw meats.

Reheating for Best Results:

The gentlest way to reheat is in a bamboo steamer over gently simmering water for 3 to 4 minutes, just until warmed through. This preserves the delicate texture. Avoid microwaving if possible, it can toughen the collagen and make the texture less silky.

Make-Ahead Prep:

You can prep your collars and ingredients up to 4 hours ahead. Pat them dry, season them, and keep them in the refrigerator on a plate covered loosely with plastic wrap. Prep your steaming liquid in a small bowl and refrigerate it too. When you’re ready to cook, everything comes together in about 20 minutes.

Food Safety Note: Fish is perishable and should never sit at room temperature for more than 2 hours. If you’re prepping ahead, keep everything cold until you’re ready to steam.

Pro Tips for Perfect Results Every Time

Even a simple dish benefits from technique refinement. Here’s what separates good steamed fish collars from extraordinary ones.

Avoid Overcooking: This is the biggest mistake home cooks make. Fish collars continue cooking slightly after you remove them from heat due to carryover cooking. When in doubt, cook for 30 seconds less than you think you need. The flesh will firm up slightly as it rests.

Use the Right Steaming Setup: A bamboo steamer basket is traditional and works beautifully, but a metal steaming rack inside a covered pot, or even a collapsible steamer basket, works just as well. The key is allowing steam to circulate freely around the collars without them touching the steaming liquid directly.

Temperature and Timing Precision: Medium-high heat to bring the liquid to a simmer, then reduce to medium to maintain gentle steam. This prevents the liquid from boiling aggressively, which can create uneven cooking and tough fish. Use a kitchen timer, don’t rely on guessing.

Check Multiple Collars: If you’re cooking multiple collars, check the largest one first. Smaller ones will likely be done at the same time or just slightly before.

Why Steaming Wins: Unlike pan-searing or baking, steaming creates a humid environment that prevents the fish’s surface from drying out. The collagen in the collar needs gentle, moist heat to render properly into that silky gelatin. High heat seals the surface and traps moisture inside, leading to dense, rubbery texture. Steaming avoids this entirely.
