Loveliness? In a sauce?  Oh, yes.  In growing up we had gravy at at least half of our meals and when I first began cooking, it was something I thought should be served as often as possible.  There was a problem, however:  I couldn’t made a smooth gravy.  Don’t laugh, but I had to strain almost every gravy I made thanks to the lumps.   So, every time I make a new sauce or a successful gravy, it makes me very joyous.
