– a glass baby food jar or similar glass jar
– VERY cold heavy whipping cream
Note: You can use larger jars, but making the butter takes lots longer.
Step ONE: Fill the jar 2/3 full with with whipping cream.
Step TWO: Shake, shake, shake! After a while, the cream will become more solid, like whipped cream. Keep shaking, and in a few minutes you’ll find a small ball of butter in your jar.
Step THREE: Drain off the excess liquid, and enjoy your butter on a slice of warm bread!
