Homemade Butter and Buttermilk
Makes about 16 ounces (2 cups) each of butter and buttermilk.
Note for recipes using homemade buttermilk: In recipes calling for homemade buttermilk, you may substitute each cup of homemade with a mixture of 1 cup of 1-percent milk and 2 tablespoons cultured buttermilk. From Daniel Patterson, the chef at Coi in San Francisco.
6 c. organic heavy cream
Salt to taste, optional
Directions
Pour the cream into the bowl of an electric mixer fitted with a whisk. Tightly cover the top of the bowl with plastic wrap and start mixer on medium-high speed. The cream will go through the whipped stage, thicken further and then change color from off-white to pale yellow; this will take at least 5 to 8 minutes.
When it starts to look pebbly, it's almost done. After another minute the butter will separate, causing the liquid to splash against the plastic wrap. At this point stop the mixer.
