Backstory: I've never really lived independently before (even during college) and I've never really had to fend for myself much, so please forgive this elementary cooking question.
I have about 1kg of ground/minced beef, I also have a large (~700g) jar of "spaghetti sauce".
I asked my parents what to do, but they were too busy to give anything more than fleeting advice. I understand I have to simmer the beef in the sauce for about an hour or two?
...but the beef's packaging label says it only needs about 7 minutes of cooking in a skillet or saucepan at 70degC/160degF (which seems a bit low to me - I thought all cooking was done at 100degC or above?). There are no instructions given on the jar of sauce.
What do I do? Who is correct, the beef packaging or my mother?
