Beetley Pete commented that he hadn’t seen a butter crock like this before and that he had watched some video on You Tube to see how it worked. I was intrigued, so I watched a couple of them myself. They made the process more difficult than I find it. They had one soften a stick of butter in a dish and then spread and pack it down into the crock.
Fortunately I had never seen the videos when I figured out how to fill the crock. I simply set a stick of butter on its end until it is softened. Then I unwrap it and using the wrapper to cover one end I smoosh it down into the crock. Ours from King Arthur flour holds one stick perfectly. No butter on my hands, no bowl or spoon to wash.
I haven’t made a You Tube video. Too much work. As you can see from the above method, I prefer the easy approach.
