Method
- Combine: Pour the heavy cream and buttermilk into a clean glass jar with a lid. Screw the lid on tightly and shake for about 15 seconds to fully incorporate. 2. Culture: Loosen the lid slightly (or cover with cheesecloth) and let the jar sit undisturbed at a warm room temperature (around 70-75°F / 21-24°C (75°F)) for 12 to 24 hours. The cream will thicken to the consistency of sour cream. 3.
- Chill: Once thickened, stir the crème fraîche, secure the lid, and refrigerate for at least 6 hours. It will thicken further as it chills.
