Bring a pot of salted water to a boil and cook the pasta according to the package directions until al dente. While it cooks, heat the olive oil and butter in a large pan or wok over medium heat, then add the onion, peppers, garlic, lemongrass, ginger, and a pinch of salt. Cook for 2-3 minutes, stirring often, until fragrant and softened.


Add the prawns to the pan and increase the heat to medium-high. Cook for 1-2 minutes, tossing regularly, just until they begin to turn pink.

Stir in the cooking sake, gochujang paste, and passata. Let the sauce bubble over high heat for 2-3 minutes, stirring well so the gochujang dissolves evenly and coats the prawns.



Taste the sauce and adjust with more salt, pepper, or ginger if needed. Drain the pasta, reserving a splash of pasta water, then add the pasta to the pan and toss until well coated. Add a little pasta water if the sauce needs loosening.



Serve hot with freshly ground black pepper. For a richer finish, add grated Parmesan; for a brighter, dairy-free option, finish with a squeeze of lemon or lime juice.
