In a fairly large pot add cranberries, sugar, orange juice, orange zest and vanilla extract. The quality of your vanilla really makes a difference, I like Madagascar Bourbon vanilla. So does my cat.

Stir it all together. Very stir. Much mix. Wow. So together.

On medium high heat, let the tasty concoction bubble until all the cranberries pop. This sounds vague, but you'll know.

Once all the cranberries have popped, let the sauce bubble for 15 minutes (or until it's a thick jam consistency), stirring occasionally.

Congratulations, you just made some fabulous cranberry sauce that even your cat has to love.
