As I have repeated many times before in my family you were required to discuss politics and religion but recipes, cooking.. no that would get you in a heap of trouble and especially how to make pasta sauce, yes sauce.
Gravy is brown belongs on mashed potatoes in beef stew on french fries and a light brown sauce encompassing one of my all time favorites veal scaloppine
Sauce is red belongs on pasta, polenta or for dipping Italian bread while the sauce simmers on the stove
My mother was religiously devoted to her cooking especially pasta sauce. She used combinations of pork and beef and added chunks of beef just for me ( I was her favorite) . She would let the sauce cool on the stove so that she could remove much of the grease that formed at the top. she made a wonderful marinara sauce. Needless to say our house was always overcrowded with visitors and the more people who visited the more animated she became....to go back to that house for just one more meal
If I called pasta sauce gravy she would have washed my mouth out with soap
