The recipe came from http://jess-inthegarden.blogspot.com/2010/03/butter.html
It was so easy and so fast.......and so good! I did add salt to mine.
And of course I had to go buy a cute little container to keep it in! The butter is so yummy but it's really hard so you have to take some out a little before you plan on spreading on toast. And I have the guard for my mixer but still had to drape a towel over to avoid the splatter.
