adding categories

I have a category of “recipes” under that I have “Vegetable Dishes” . I posted a vegetable recipe to “Vegetable Dishes”. It shows up on the main page which I do not want. The category “Vegetable Dishes” shows up under category which I want and you can link to the recipe. How can i keep it from showing up on the main page? I only have one page on my web site and that was the default.
