We have been meaning to try and make our own butter for some time. Following a trip to our local shop, we bought some thick cream and gave it a go.
The branded crackers are optional. After hand whisking the cream for some time, I got out the electric mixer and the cream split after a few minutes. Washing as much butter milk out in a bowl of iced water, it was then shaped into a block and tasted. Jolly nice it is too.
