This would be how you would make whipped cream, it will look like that. You will go past the whipped cream stage and you will notice that it will start to separate. When it looks like this then it is done. Buttermilk and butter.
Scoop out the butter and pour the buttermilk in a jar. Wash the butter in cold running water and work it a little until the water runs clear. You can add herbs and freeze it if you want. Use the buttermilk for baking see our Donut Muffin recipe.
We also made some fresh English Muffins to go with the butter.
This was a website that we found. It also has some suggestions on books.http://www.webexhibits.org/butter/index.html This was a fun and easy project for the kids to learn. You can explore history and science.
