Ingredients

• 1 cup Heavy cream
• 2 tablespoons Buttermilk

Directions

Step 1

In a clean glass jar or bowl, combine 1 cup of heavy cream and 2 tablespoons of buttermilk.

Step 2

Stir the mixture well until fully combined.

Step 3

Cover the jar or bowl loosely with a clean kitchen towel, cheesecloth, or plastic wrap. This allows air to circulate while keeping contaminants out.

Step 4

Let the mixture sit at room temperature (preferably between 70-75°F) for 24 hours. Avoid disturbing it during this time.

Step 5

After 24 hours, check the mixture. It should have thickened to a creamy consistency and developed a slightly tangy flavor.

Step 6

Once thickened, stir the sour cream gently to ensure even texture.

Step 7

Transfer the sour cream to an airtight container and refrigerate for at least 2 hours before use. Refrigeration will stop the fermentation process and enhance its flavor.

Step 8

Store in the refrigerator for up to 2 weeks. Stir before each use if necessary.
