Save cookies between two curl requests

I know that using cURL I can see my received cookies / headers by using

curl --head www.google.com

And I know that I can add headers to my request using

curl --cookie "Key=Value" www.google.com

I am currently working on testing an issue which requires persistent cookies, and there can be a lot of them.

How can I efficiently preserve cookies between two cURL requests?

If possible using a temporary file for storage.
