I can't believe it's butter

So before the hubby left for AK we were going to make butter, for fun, but the cream got lost and forgotten about in the fridge.

I saw the cream and got it out and started making butter and then realized that the expiration date was today's date.  Phew!  Nick of time baby!  Nick. Of. Time.

I have a Tupperware thingy that I've used before to make butter and it was working just fine...

cream, Tupperware thingy, salt
