La préparation

Étape par étape

1. 1

   Sanitize a clean glass jar and its lid by rinsing them with boiling water, then let them cool completely to room temperature.

   Environ 2 min

   Note du chef : Proper sanitation prevents unwanted bacteria from spoiling your cultured cream.

2. 2

   Pour the whole milk and heavy cream into the cooled jar.

   Environ 1 min

3. 3

   Add the buttermilk, which will act as the starter culture.

   Environ 1 min

   Note du chef : Ensure your buttermilk contains live cultures by checking the label, as this is essential for fermentation.

4. 4

   Stir the mixture gently with a clean spoon for about 15 seconds, just until everything is combined.

   Environ 1 min

   Note du chef : Avoid over-mixing, as this can interfere with the setting process.

5. 5

   Cover the jar's opening with a coffee filter or a double layer of cheesecloth and secure it with a rubber band.

   Note du chef : This breathable cover allows gases to escape while keeping contaminants out.

6. 6

   Let the jar stand undisturbed at a consistent room temperature (around 20-24°C) for 12 to 24 hours, away from direct sunlight.

   Environ 12 h

   Note du chef : The fermentation time will vary based on your room's temperature; a warmer room will speed up the process.

7. 7

   Check the mixture; it is ready when it has visibly thickened to a soft-set, yogurt-like consistency and has a pleasant, tangy aroma.

   Note du chef : If it still looks like milk, let it ferment for a few more hours.

8. 8

   Remove the cloth cover, screw on the jar's airtight lid, and transfer it to the refrigerator.

9. 9

   Chill for at least 6 hours, or overnight, to allow the gräddfil to set fully and for the flavors to mellow and develop.

   Environ 6 h

   Note du chef : The cream will thicken significantly more as it chills.
