It's a good thing when you learn how to make sour cream from scratch.
This sour cream is delicious and makes food so flavorful. I include many homemade condiments too.
HOMEMADE SOUR CREAM FROM SCRATCH
1 cup heavy cream
1/4 cup sour cream or homemade buttermilk (or even white vinegar will work)
In a screw-top jar, or mason jar with lid, combine the heavy cream and sour cream (or buttermilk). Shake the ingredients up a bit to thoroughly mix and let stand, covered, at room temperature for about 24 hours or until it becomes very thick.
You can store your sour cream in the refrigerator in the original jar you mixed it in (or use some other resealable container) for up to one week.
Make sure that your sour cream is well chilled before using. If you want to make a lighter sour cream, substitute whole milk for 1/2 cup of the heavy cream.
