I have ground beef and tomato sauce, I want to make spaghetti. I already know how to make the noodles BUT, I don't know how to make the meat sauce.

I was told to brown the meat, drain the fat and then throw in the sauce and cook it for a bit. I just don't know at what temperatures and for how long. And what is an easy way to drain the fat? With a strainer?

Help /ck/!
