Sour cream is a popular dairy product that is used in many dishes, from dips and dressings to baked goods and desserts. While you can easily find sour cream at your local grocery store, making your own sour cream at home is a simple and rewarding process. In this article, we will go over the steps to make sour cream from scratch.


  • 1 cup heavy cream
  • 1 tablespoon buttermilk


  1. Start by sterilizing all of your equipment. You will need a glass jar with a lid, a whisk, and a measuring cup. Boil some water and pour it over the jar, lid, and whisk to sterilize them. Let them cool before proceeding.
  2. Pour the heavy cream into the sterilized jar.
  3. Add the buttermilk to the cream and whisk it thoroughly to combine.
  4. Cover the jar with a lid and set it aside in a warm place. The ideal temperature for sour cream to form is around 70-75 degrees Fahrenheit.
  5. Let the cream sit undisturbed for about 24-48 hours, checking on it occasionally. The cream will thicken and become sour during this time.
  6. Once the cream has thickened, give it a stir and taste it to see if it is tangy enough. If it is not sour enough, you can let it sit for a few more hours until it reaches your desired level of tanginess.
  7. Once your sour cream has reached the desired level of tanginess, store it in the refrigerator. It will keep for up to two weeks.


  • Use a glass jar with a wide mouth for easier whisking and stirring.
  • If you don’t have buttermilk, you can use a tablespoon of white vinegar or lemon juice instead.
  • Make sure the cream you are using is not ultra-pasteurized, as this can affect the sour cream-making process.
  • The longer you let the cream sit, the thicker and tangier the sour cream will become.
  • You can adjust the amount of buttermilk you use to control the level of tanginess in your sour cream.

In conclusion, making sour cream at home is a simple process that requires only a few ingredients and some patience. Homemade sour cream is fresher and more flavorful than store-bought sour cream, and it can be used in a variety of recipes. So next time you need sour cream for a recipe, consider making your own and enjoy the delicious taste of homemade goodness!
