Ina Garten Homemade Chicken Stock

Good morning.  There is a big pot of homemade chicken stock (see above) simmering on the stove and the smell is delicious.  It is kind of a welcome home smell for John who has been out of town for a few days.
Yesterday on my way home from up north I stopped at Whole Foods to get groceries.  I knew I wanted to make some stock so I checked my Iphone for Ina Garten's recipe to make sure we had all the ingredients needed.  Well, for the life of me I couldn't find it.  As a result I am going to post it here then pin it to Pintrest so I am never without the recipe again.  I make stock occasionally just using what I have but I picked up Ina's, "barefoot contessa ~ how easy is that?, cook book at TJ Max the other day and wanted to try her recipe.  I have one other barefoot contessa cook book and found her recipes in it to be scrumptious.
