Does she also rinse off ground beef when she is done cooking it?

[Yosemitest]

Probably, but I'm guessing.
Don't tell her, but if anyone can ruin a good piece of beef, she can.

Actually I do that when I make meat sauce ( can never understand why they call it meat sauce when they put it on Pizza when it's just plain ground beef ) for putting it on pizza or sloppy Joes.
I hate it when the oil from the meat comes running down your arm when eating sloppy Joe's, and yes, I know, that's why they are called sloppy Joe's.
