Q&A: Is it illegal to put a recipe from Food Network in a cook book?

Question by Amie87 AKA Mrs. L: Is it illegal to put a recipe from Food Network in a cook book?
I am making a cook book of all of my families favorite recipes, I have plenty of my own recipes to put in it, but there are also a few recipes that I have gotten from either food network or various cook books down the line. Would it be illegal to use the recipes that I use from food network or other cook books in my cook book. I would of course cite where I got the recipe but, I am still unsure
