Introduction: Easy Homemade Sour Cream

About: Hello and Welcome to In the Kitchen With Matt. I am your host Matt Taylor. My goal for the show is to teach you how to cook really good food at home for cheap. Eating out everyday can get expensive, but it doe…

In this instructable, I will show you how to make sour cream. This recipe for homemade sour cream is really easy to make, if I can make it, you can make it! It will taste a bit different then the kind you buy at the store and it won't be quite as thick, but it is still pretty amazing! Especially if you don't have access to it. Let's get started!

Don't forget to check out my other instructables.

If you have any questions or comments, put them down below and I will get back to you as soon as I can.

Follow the easy steps or watch the short video tutorial, or do both!

Step 1: Ingredients/Tools

Print the recipe here on my website.


  • 1 cup of heavy whipping cream
  • 1/4 cup of milk (whole milk preferably)
  • 2 tsp. of white vinegar (or 2 tsp. of lemon juice)


  • Jar (mason jar works great)
  • Thin towel or paper towel
  • Rubber band or twine
  • Spoon

Step 2: Add Ingredients to Jar

First let's take a clean jar and add our whipped cream, milk, and vinegar (or lemon juice).

Step 3: Cover and Shake

Next let's cover the jar with a lid and shake it up a bit to make sure it is all incorporated. Don't shake it up too much! We don't want it turning into butter. haha

Step 4: Cover and Leave Alone

Next we take the lid off and cover the top with a thin towel or a paper towel (kitchen towel). Use a rubber bad or some string to keep it in place. Now just let the jar sit out at room temperature for about 24 hours until it thickens up.

Step 5: Stir, Pour, and Serve

After it has rested for about 24 hours, you will notice that the top is thick, and at the bottom it will look watery, that is normal for that separation to occur. Just take a spoon and stir it all together. Then pour it into a bowl to be used, or keep it in the jar you used. Use this on baked potatoes, in baking, however you would normally use sour cream. Enjoy!

***When covered it will last about a week in the fridge.
