What would this sauce be called?
Using the meat juices from cooking is a jus :) adding wine along with the aromatics might change it to be a "red wine jus" or I've also seen a "port jus", or the jus could be used in a Madeira sauce, etc.


  served in the natural juices that flow from the meat as it cooks.
