Bring a pot of salted water to a boil and cook the pasta until al dente according to the package instructions. Reserve a small splash of pasta water, then drain.


While the pasta cooks, heat the olive oil and butter in a large pan over medium heat. Add the onion, red and green peppers, ground lemongrass, ground garlic, and ground ginger, then cook for 2 to 3 minutes until fragrant and softened.

Add the prawns to the pan and increase the heat slightly. Cook for 1 to 2 minutes, stirring often, until the prawns just begin to turn pink.



Stir in the cooking sake, gochujang paste, and passata. Cook over medium-high heat for 2 to 3 minutes until the sauce is glossy and the prawns are fully cooked through.



Season with salt and pepper to taste, then add the drained pasta and toss until evenly coated. Loosen with a little reserved pasta water if needed, then serve hot with black pepper, Parmesan, or a squeeze of lemon if desired.
