Add the cream and salt to a mixer with a whip attachment. Whip the ingredients until the cream separates into liquids and solids. This can take around 20 minutes to complete. First, the cream will become whipped, then it will gently separate into small solids, and then it will fully separate.
Step 2
Pass the contents of the mixer through a fine mesh strainer. Discard the liquid. Use your hand to squeeze any additional liquid out of the solids. Shape the butter into a rectangle, wrap it in wax paper and refrigerate. You can store your homemade butter in your freezer for the longest shelf life. It will be easy to cut into when you’re ready to use!
