In a thick bottom pan, heat butter with olive oil. This combination creates a rich base for your risotto. As the butter melts, let it bubble gently without browning.
Add the diced onion and cook until it becomes translucent. This step is crucial as it builds the flavor foundation, making sure the onions are soft but not browned.
Incorporate the grated garlic and keep stirring. Be attentive as garlic cooks quickly and can burn easily, which would add bitterness to your risotto.
Stir in the arborio rice, coating each grain in the buttery mixture. Toasting the rice slightly enhances its flavor and prepares it for absorbing the stock.
Begin adding the warm stock gradually. Pour in just enough to cover the rice and let it reduce. This slow process is key to achieving that creamy texture.
As the rice absorbs the stock, continue adding more stock bit by bit until the rice is al dente and creamy. Keep stirring to unleash the starches from the rice.
Once the rice has reached your desired texture, mix in the cooked crab. Give it a few moments to heat through, letting the flavors meld together.
Add the prawns, lemon zest, and lemon juice. The prawns should turn pink and opaque, signaling they’re cooked. This addition brightens the dish beautifully.
Finish by stirring in the parmesan cheese and a piece of butter for extra creaminess. This final step adds depth and richness to your risotto.
In another pan, add a pinch of sea salt and a drizzle of olive oil. Place the sea bream skin side down, cooking until it’s crispy. Flip it over and cook until it's done, about a few minutes.
Divide the risotto between bowls, top with the perfectly cooked sea bream, and serve it immediately while it’s warm and creamy.
