Place your stock and Peat’d Tomato Sauce in a small saucepan over medium heat. Bring it to a simmer, then reduce the heat right down and leave it simmering as we are cooking.
While waiting for the stock, chop the onion and garlic up finely.
Season the fish fillets with salt and pepper and set aside.
Let's Cook the Risotto
Heat the olive oil on low heat in a large saucepan and sauté the onions for 2 minutes until softened, stirring regularly to stop them burning.
Add the garlic, stir for 30 seconds, then add the rice and coat with all that fat, stirring well. Toast the rice for 2 minutes, until the edges turn a little translucent.
Pour in the wine, increase the heat to medium and cook for 2 minutes.
Add 2 ladles of the simmering smoky tomato stock and stir gently. Keep stirring regularly until the rice has absorbed the stock. Repeat this process for 15 minutes. You may not use up all the stock.Check your risotto, it should be done at this stage. Is the rice cooked through with just a little bite to it? If not, add 2 more ladles and cook until the stock has been absorbed. And another 2 ladles, if necessary. Now it should be done. Take it off the heat and leave to rest for 2 minutes.
Let's Cook the Fish
Let’s attend to the fish. About 10 minutes into cooking the risotto, heat 2 Tbsp of vegetable oil in a large frying pan over medium-high heat. Place the 4 fish fillets skin side down and cook for 2 - 3 minutes, until you have a golden, crispy skin. Don’t forget the risotto while you’re frying the fish.
Turn the fish over and cook for another 3 minutes or so until your fish is cooked through. The time will depend on the thickness of your fish. Take them out onto a plate when done, to stop them over cooking.
Time to Dish Up
Back to the risotto. After the 2-minute rest, add the grated parmesan and 2 Tbsp olive oil and stir vigorously with a wooden spoon until the parmesan is all blended in. This is called mantecatura and is the final step in cooking risotto, creating that creamy emulsion that the Italians call all’onda.
Serve the risotto onto 4 plates and sprinkle some truffle dust and plenty of freshly ground black pepper.
Top with a fish each, skin side up and serve immediately.
