A complete tutorial for how to make homemade butter and cultured buttermilk. Learn how to make your own butter as a fun and useful project to do with kids. All you need is heavy cream and salt. Use a food processor, blender, butter churn or mixer.
Blend heavy cream. Pour entire carton of heavy cream into a food processor, blender, or butter churn. Blend for about 10 minutes or until the fat separately completely from the liquid milk. You should see two distinctly different substances and then you know you're ready for the next step.
Drain away buttermilk. Next, drain the milk into a mason jar. This is your buttermilk!
Rinse butter. Once you've drained all the milk, rinse the fat to flush any extra hidden milk from it. To rinse, add a cup of very cold water and blend. Pour off the watery milk. Go ahead and pour it down the drain, this stuff isn't worth saving.Repeat until water runs clear.
Squeeze out remaining liquid. Take the chunk of butter and wrap it in cheese cloth. Knead butter to get out any remaining liquid. Rinse under cold water while kneading.
Season with salt. Stir or knead in salt to taste.
Shape. Use clean hands to shape butter into sticks or whatever shape you prefer.
