Making butter at home is an easy process and a fun activity to do with kids. There are a few different ways to do this, but all of them follow the same principle. Agitate the cream enough to dislodge the fat from the water. Pick a method that suits you and enjoy freshly churned butter
Water as needed
Pour the Chilled cream into a bottle filling less than half the bottle. Close with a tight-fitting lid.
Shake the bottle vigorously. After about 5 minutes the cream seems to have increased in volume. Keep shaking and in about 20 minutes you will have a solid lump formed in the bottle. Shake a few more times until butter pieces coalesce into one.
Pour the cream into the mixing bowl. Fit the mixer with the whisk attachment and start whipping at low speed. After a few minutes increase the speed to medium. At this point, you can add some cold water to speed up the process. Continue whisking as the whipped cream changes color and the butter begins to separate. Stop when all the butter separates into clumps and the pale leaving white liquid at the bottom of the bowl.
Blender / Food Processor
Add cold water to the mixer immerse the blades by about an inch. Add the cream, cover with the lid and start pulsing for 5-second intervals. In about a minute the solids will start separating. Keep pulsing a few more times until all the solids float up into a yellowish mass.
Add ice chips to the blender if needed to keep the contents cool.
Rinse and Store
Scoop the butter into another bowl and pour water over it. Press the butter with the back of a spoon to release any trapped air and buttermilk. Drain the water. Repeat this process a few more times until the water runs clear.
Drain the water and form the butter into any shape you prefer. Place in an airtight container. Refrigerate if not using the same day.
Use heavy whipping cream or cream collected on top of whole milk /yogurt. The latter will be thicker than heavy cream so add some cold water to thin it.
Keep the bowl and cream cool for faster results.
It is better to use room temperature water for rinsing butter.
