Reduce heat and simmer, add cumin, granulated garlic, granulated onion and salt. NOTE: To me the cumin is what really takes this to the flavor I'm looking for, but if you are not that crazy about cumin, start with a lesser amount. Simmer on low for about 15 min. Taste and re-season to your liking. Allow to simmer another 10 min or so. Keep stirring occasionally, if sauce is too thick, add a little more stock or water.
