Recipe Plagiarism?!

Recipe Plagiarism?

I am going to start a site for my friends and family to share recipes of my own and recipes I have found in books and online. My question is: Can recipes be plagiarised? Obviously, any recipe you look for online (or books) , there are duplicates or even thousands of recipes with the same name,idea or even wording. I plan to list the site or book in which I found them, but if someone comes across them, can I get charged with plagiarism, even though I have sited my source? I don't understand how any one person can own a recipe. I have tried to do some research, and it states that even changing the ingredients around it does not make it yours. Obviously I can make a recipe for anything, but like I stated above, there are thousands of variations. Can someone please help me with this? Thank you.

If you are NOT going to charge for the information, then no problem.
You may want to consider just putting a quick disclaimer on your site that expresses that your information is a "compilation of gathered works" and that "you do not claim to be the original author of anything material contained there in."
