While you would not want to make all your family's butter this way, this will show you how butter is made.

You'll need:

• A jar with a tight-fitting lid
• A carton of cream, not sweetened
• A bit of salt- optional
• Some patience

Here's what to do:

1. Pour the cream into the jar until it's half full.

2. Tightly screw the lid on the jar.

3. Shake the jar.

4. Shake it some more!

5. After a while you will notice that yellow butter has formed.

6. Add a tiny amount of salt if you like.

7. Spread it on some bread. Yum!
