A friend of mine made butter by putting a pot of cream in her KitchenAid for 10 minutes and said it was fantastic. This is something I need to do - if there's a new way of using my KitchenAid then I want to do it! My question is - how long do you think it would keep? My friend said she thinks it would last as long as normal butter but I'm a bit dubious about that - the cream itself only keeps for 3 days once opened so surely it won't be any different just by being whizzed up into butter? Guess I could freeze it in small batches though.
