I started by filling two jars half-way with heavy whipping cream. I made sure the lids were sealed TIGHT. While the girls shook them and rolled them and turned them this way and that, we talked about milk & butter & how our grandparents and great-grandparents used to make butter. They decided this way was much easier and much more fun. In the jars above, you can see they had been shaking for a while. The cream went from thick liquid to creamy like pudding to a big lump in watery milk. That's butter!
Here, we poured the contents of the jar into a strainer with a clean bowl underneath. The photo below shows the buttermilk that was strained off. DH used it later to make biscuits.
After adding just a pinch of salt, here is the finished product--BUTTER! And it was delicious!
