How I Developed This Recipe
So far, I have developed recipes for curry using the roux cube box, beef curry, and chicken katsu curry, but the one I like the most is seafood curry.
This recipe was designed to maximize the natural flavors of fresh seafood. Some steps might seem time-consuming, and some ingredients might seem unusual, but each element is there for a reason and helps create the perfect dish.
I grew up in Japan and have enjoyed countless plates of curry rice over the past three decades, so I can confidently say this recipe produces something extraordinary.
There are probably not many people in Japan who make it this way. Please enjoy this one-of-a-kind seafood curry!


Key Ingredients & Substitution Ideas
- Seafood Selection: I used a combination of shrimp, scallops, and tuna as the base. Feel free to add local seafood like squid or shellfish—they’ll give your curry a great umami boost. Just pick whatever’s freshest at your local market!
- Japanese Curry Powder: For authentic flavor, use a Japanese-style curry spice mix. I either recommend trying my homemade curry mix recipe, or S&B’s Oriental Curry Mix. But you can still make this using regular curry powder from your supermarket.
- Dashi Stock: This essential Japanese soup stock is the building block of our curry’s flavor profile. While making your own dashi is the best way to go, quality dashi packets are a great alternative.
- Squid ink (squid ink): This special ingredient does two things: it deepens the seafood flavors and it gives the curry a gorgeous dark color. Just a little goes a long way! If you can’t find it, the curry will still be great without it.
- Japanese Rice: Short-grain Japanese rice is the ideal side to go with this curry. For more detailed instructions on selecting and preparing the perfect rice, check out my comprehensive white rice cooking guide on the blog.
- Secret Flavor Enhancers: This special blend includes white wine, garam masala, instant coffee powder, honey, blueberry jam, soy sauce, and Worcestershire sauce. A small amount of each ingredient is important for creating our curry’s complex flavor profile.
- Other ingredients: Olive oil, unsalted butter, onion, garlic, ginger, cake flour (or all-purpose), bay leaf.

STEP
Ingredient Preparation
Next, pour the soy sauce over the tuna cubes, making sure they’re all evenly coated. Let them marinate while you get the other components ready.


Start by heating a wok or large frying pan over the lowest heat setting. Add the olive oil and the reserved prawn shells. Let the shells soak in the oil for about 10 to 15 minutes, giving it a stir now and then.


This gentle extraction process draws out the sweet, briny essence of the prawns, creating a flavorful base for the dish.
Take the prawn shells out of the infused oil, but keep the tasty oil in the wok.
Turn up the heat to medium. Next, add the prawns, scallops, and marinated tuna to the wok. You can also add your root vegetables here (I used carrot and potatoes) so that they take on some of the flavor from the seafood.


Just a heads-up: We’re saving the marinade liquid for later. Cook just until the seafood starts to look opaque, which should take about 2-3 minutes.


Once done, take it out of the wok and set it aside.
