Step 1

Combine all ingredients in an airtight mason jar with a lid.

Step 2

Secure the lid and begin shaking the mason jar until the cream thickens (about 2 minutes).

Step 3

Get a cheesecloth or kitchen paper and place it over the open mason jar.

Step 4

Leave for 24 hours in a cool, dark place.

Step 5

After 24 hours, remove the cheesecloth/kitchen paper and give the mixture a final stir. It would have thickened significantly to a sour cream texture.

Step 6

Secure the lid back on and store it in the fridge for up to 1 week.
