Whip the cream

• Pour the cold heavy whipping cream into the blender fitted with the whisk attachment.
• Blend and let it whip until it turns into whipped cream, like cake frosting.

Keep blending until the butter separates

• Let the blender keep running without stopping.
• The cream will break and turn into butter, with buttermilk left in the bowl.

Save the buttermilk

• Pour off the buttermilk left in the blender bowl into a jar.
• Keep it to make ranch dressing or other recipes; do not throw it away.

Squeeze and rinse the butter

• Squeeze out all the remaining buttermilk from the butter.
• Rinse the butter under cold water until the water runs clear.

Salt and serve

• Place the butter on a plate or in a dish.
• Add as much salt as you like and mix it in.
