Milk kefir grains could also be used to culture the cream by adding one teaspoon to 1-4 cups of cream. Culture for 12 hours. Now proceed to turn the cream into butter by placing it in the freezer for a few hours. Remove it from the freezer then put the cream in a bowl and use a mixer to mix.

Wash the butter with clear water then press out the buttermilk until the water starts to run clear.
