As far as food is concerned, there are several similarities in the food tradition of Italy and Spain: we both use olive oil rather than butter, we both make large use of tomato sauce, onions and the aromatic herbs of the mediterranean basin. Some local products are also very smiliar such as the Spanish Jamon (Serrano and Iberico) and the Italian Prosciutto Crudo (Parma and San Daniele being the most popular, although an immense variety is available).
You can actually make risotto with any ingredient you like: cheese, wine, sausage, vegetables, mushrooms and so on. There is basically no food wich cannot be used for making a good risotto, which is is pretty good because all of us are allowed to make our own special risotto regardless if we are omnivore, vegetarian or vegan: risotto is for everyone.
Have you ever wondered why Risotto is one of the most iconic Italian recipes? First of all Risotto is mostly a concept rather than a recipe. It’s a cooking technique and that is why you can make it in a million different ways, some of which are “standards”, you might say, while some others are fully open to your creativity.
