Gather supplies. Heavy Whipping Cream 8 ounces/1 cup, Kosher Salt 1/4 teaspoon, Blender, Strainer.
Measure out 8 ounces/1 cup of Heavy Whipping Cream.
This amount makes one "stick" of butter.
Pour into blender.
Blend till gets thick. Mine took about a minute. Check it, you can add sugar to this and have whipped topping. But we want butter. So keep blending.
After another minute of blending, it starts to separate and looks gritty.
Add 1/4 teaspoon of Kosher salt.
Blend another 10 seconds and the liquid is drawn out.
Dump all in strainer.
Mash the butter to drain all liquid.
This liquid is Buttermilk!
Now you've got Fresh Butter...
...And Buttermilk! Store buttermilk in freezer to add to recipes later.
I love these little freezer cups made from Ball!
You could place this is a fancy form or make a log with plastic wrap. I just put in a sealed bowl. It won't last that long here! Enjoy!
