pour the heavy whipping cream into the stand mixer using the whisk attachment
set mixer to medium speed (i used level 4 on my kitchen aid)
let it mix for approximately 20 minutes until you see butter in the whisk and a milk in the bowl. pay attention towards the end because the milk started splashing everywhere for me
strain the milk and save to make biscuits, pancakes, ranch dressing, cookies....etc!
form your butter into a ball and place in an ice bath to remove any remaining butter milk
once clean, add salt and mix well
place in a bowl or a silicone mold and refrigerate until use!
