Kitchen Tip

Not sure if this is a well know tip, but no one has ever told me, so I thought there might be a few of you out there that might not know!
I am not a huge meat eater, and I really really don't like chunky ground beef.  I like my ground beef to be soft and small pieces, so what I do to get this is make sure my meat is completely thawed, then I break it up with a wooden spoon and then add about a cup of water per pound.  I don't know scientifically what it does, but every time I do this my meat comes out soft, moist and small, usually the water just cooks out, but if you have some leftover after cooking then just drain it off.
