How to Make It
In a frying pan over high heat, sauté the chopped garlic in a little olive oil for a few seconds, making sure it does not burn. Add the onion, reduce the heat to low, and sauté until golden and transparent, approximately 10–15 minutes. (It’s important to sauté the garlic before the onion as this will help to release its aroma.)
Before cleaning out the inside and bones of the cuttlefish, carefully remove the silver sac of ink from the middle of the cuttlefish, making sure not to break it, and set it aside. Cut the cuttlefish into 1 centimeter (1/2 inch) cubes.
Add the diced cuttlefish to the sautéed garlic and onion and season well with salt and pepper. Sauté the cuttlefish until all the liquid that has been released has evaporated and the cuttlefish starts to stick to the bottom of the pan, caramelising slightly. Add the tomato paste and cook for a few seconds, then add the white wine and cook until the liquid has almost completely evaporated. Add the fish stock or water, 1/2 tablespoon of the cuttlefish ink, and adjust the seasoning. Leave to simmer on low heat for 10 minutes.
Add the rice and cook for 16 minutes, stirring the risotto constantly until it is done (the rice should be cooked but still slightly firm). If the risotto is too thick, you can add some more fish stock and olive oil at the end. Add more seasoning if needed and serve immediately.
