My grandmother would go out in her front yard, grab a chicken, wring its neck, chop it's head off, pluck it, WASH IT, and throw it in a pot of boiling water or if she were going to fry it, cut it into pieces. Nobody ever got sick off her chicken.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
