For some reason, a lot of people think butter is a lot more complicated than it is. I don't know why. Maybe it's images of butter churns, or something about how is comes all packaged up in nice little bricks.
Repeat after me: Butter is SIMPLE! Butter is EASY!
That's all, folks!
Put about 1 cup heavy cream in a glass jar. Close it, and give it to your tot.
Roll the jar around on the floor or shake it for about 10 minutes. It will slowly thicken, then quickly separate into butter and buttermilk. It will get quiet as it thickens, but when it separates you'll hear the buttermilk sloshing around.
Dump the whole jar in a strainer. Save the buttermilk for tomorrow's pancakes :-)
Rinse the butter with cool water.
That's it! It takes about 15 minutes total, and tastes DELICIOUS! Now you just need some bread!
