Let's Shake it Up!
This aim of this demonstration is to separate cream into two parts, a solid and a liquid.
What you need:
- 1 carton of double or single cream
- 1 jar with a lid
- 1 glass
- 1 plate
- Serious elbow grease!
Tip - If you have a plastic container add a clean marble to your mixture before you start shaking to speed up the process.
- Leave the cream out of the fridge for about an hour before you start.
- Fill your jar half full of cream and put on the lid nice and tight.
- Put on some music
- Shake the cream up and down
- After a couple of minutes, the cream will thicken, and you won't feel liquid sloshing around anymore. Keep Shaking!
- This could take awhile so if your arms get tired get someone else in your house to take over for a while.
- After a few more minutes, you will hear the liquid again. Don’t worry, the mixture is not turning back into liquid cream, it is starting to separate. Keep shaking!
- After 10 – 15 minutes you should be able to feel that there is now a large solid lump in the jar along with some liquid.
- Open the jar and pour the white liquid into a glass. The yellow solid lump is butter, shake it out onto a plate.
You can use the buttermilk in recipes such as pancakes, buns, or bread (a lovely bread recipe below).
Give the butter a rinse under some water to remove any buttermilk, knead it as you rinse. This stops the butter going rancid quickly. You can add a pinch of salt to make it a little tastier and then your lovely fluffy butter is ready to eat.
The Science Bit - Cream is a mixture. It is made of tiny drops of water mixed with fat droplets and protein. Shaking the cream in the jar makes the fat droplets stick together, forming butter. The liquid part has the protein and that is the buttermilk.

Bit of a Butter Tongue Twister
Betty Botter bought some butter, But she said, "This butter's bitter!
If I put it in my batter,
It will make my batter bitter.
But a bit of better butter
Will make my batter better."
So, she bought some better butter,

And it made her batter better!
So 'twas better Betty Botter
