How to Make Creme Fraiche

Step 1

Add the 3/4 cup of heavy whipping cream to the jar.

Step 2

Next, add the 2 1/4 tsp of buttermilk or plain yogurt and stir well.

Step 3

Place the lid tightly on the jar, and leave out at room temperature, open the jar and check to see if the cream has thickened at the 12 hour mark.

Step 4

If the cream is not thickened, wait another 12 hours and check again.

Step 5

If after 24 hours it has still not thickened, continue to check every 12 hours. The process could take up to 36 to 48 hours depending on the temperature inside your house.

Step 6

Once the cream has thickened quite a bit, give it a good stir and refrigerate at least four hours to finish the thickening process before using. It will keep for up to two weeks refrigerated.
