You Already Have The Simple Ingredients Needed For Homemade Sour Cream
BY JOSIE DLUGOSZ
A staple ingredient for many Americans, sour cream is also super easy to make at home, and it only requires two other household ingredients: heavy cream and vinegar.
Sour cream is dairy cream fermented by lactic acid bacteria, so when making it at home, simply add an acid of some sort to heavy cream. For this, vinegar is a popular choice.
Whisk a cup of heavy cream with a tablespoon of vinegar or, alternatively, lemon juice, directly in a jar. Then, cover the top with a paper towel and secure it with a rubber band.
Let the mixture sit out at room temperature for 24 hours. It should have now thickened a bit, after which you can place it in the refrigerator to chill and use the cream as needed.
