In the bowl with a mixer add the heavy cream and mix on high.

Whip it with a whisk attachment until it turns to whipped cream, then keep mixing.

This will take about 3 minutes.

The cream will separate and look like scrambled eggs, then keep beating and then the water will separate from the butter and the liquid is actually buttermilk.

After the buttermilk forms, remove the bowl from the mixer and fill bowl with cold water.

With your hands, you will now squeeze the butter together to form a ball, keep forming it under cold running water, this will remove any tangy buttermilk.

When the water runs clear, place the butter into a glass dish or wrap it in parchment paper.
