Ingredients:
- 1 pint (473ml) Heavy Cream (at least 36% milk fat) - Pasteurized, but NOT ultra-pasteurized
Instructions:
- Chill the heavy cream and your chosen method (stand mixer bowl, jar, or food processor bowl) thoroughly for at least 30 minutes before starting. This helps the fat molecules solidify.
- Stand Mixer: Pour the chilled cream into the mixer bowl and beat on medium-high speed until it goes through stages: whipped cream, then starts to look curdled and separated. Continue beating until solids (butter) form and separate from the liquid (buttermilk).
- Jar: Pour the cream into the jar, seal tightly, and shake vigorously for 20-30 minutes. Take breaks as needed! The cream will go through similar stages as the mixer method.
- Food Processor: Pour cream and process.
- Pour the mixture into a sieve or cheesecloth-lined bowl to separate the butter from the buttermilk. Reserve the buttermilk for baking or other uses!
- Gently rinse the butter under cold running water, kneading it with a rubber spatula to remove any remaining buttermilk. This is crucial for extending its shelf life. Continue rinsing and kneading until the water runs clear.
- Shape the butter into a log or desired form. Wrap tightly in parchment paper or plastic wrap and store in the refrigerator for up to 2 weeks, or in the freezer for up to 3 months.
