Yum?

I'd forgotten I had some ground beef in the fridge I bought on Sunday, and discovered it'd gone a little grey on the outside. I sniffed it, but couldn't detect anything wrong with it, so decided to cook up some quick and easy spaghetti sauce.

Now that it's on the stove, I'm a little afraid to try it. My sinuses are all stuffed up, and I think my sense of smell is botched. So I'm staring at a full pot of spaghetti sauce, and there's no one in the house to tell me, "Mmm, that smells delish," or "FOR THE LOVE OF ALL THAT'S HOLY, WHAT THE FUCK ARE YOU COOKING, A THREE-WEEK-DEAD CAT?"

Do I try it? Do I leave it?
