Everyone has their own style, but sometimes it helps to define it. When it comes to creating your own food style, there is an additional problem: The style needs to be a healthy one as well or you will develop health problems later on. Thankfully developing a new style is not that hard. It just takes a theme in mind and having some fun.
When you create your own style, make sure that all of the food groups are well represented. You also do not want a diet of limited items or you will get bored of the food rather quickly. It also helps to look at foods and recipes already extant in order to help you define your style even better; those choices help to add certain flavors to your style, giving it some texture and better defining it. As long as the flavors are complementary the style will prove to be a strong one. Obviously a few shocking choices can work, such as the sourness of sauerkraut in an otherwise sweet style, but make sure that there is something thematic with all the choices or it may seem like a number of random choices.
Finding your own food style can be a lot of fun, especially for someone who knows a lot about food. The biggest problem will be defining a theme and sticking to it, especially if that theme is extremely limited, such as a theme based on a specific Italian city. However, with a little imagination and a lot of research, it is possible to create a fun style that may even take off on its own, especially if the style happens to fit into some fad at the moment. Even if the style is for personal reasons, put some thought into it and you should be able to enjoy it for years.
