I made this up tonight when I was making Recipe #420618. After I browned the chicken, I didn't want to waste all the great flavour that was left in the pan. You can use whatever herb you want. I chose rosemary because it was in the chicken recipe and it just tastes good! I recommend making this if you have browned some meat. It just absorbs the flavour nicely. Of course you can make this in a saucepan, but this was originally created to use the pan juices. Enjoy!
