The first time I took homemade butter to a family dinner (I do believe it was Thanksgiving Day a few years ago) my sweet brother asked me if I now had a cow living in my back yard. Although I do not have a cow yet, some day I will my friends! Alpacas need friends too.
Until then, I buy the cream at the store....the way of the city girl.
This is what it's going to look like when it's done (before pouring out the buttermilk). You'll know it's done because you'll be able to hear the butter clunking around the container.
