This Homemade Sour Cream Recipe has two ingredients and only takes a couple of minutes to prep. It’s foolproof, creamy, and great if you prefer to have control over what ingredients go into your food.

Have you ever needed sour cream and discovered you were out? I sure have, and I was so excited that there is a simple way to make your own sour cream with two very basic ingredients.
There is a slight difference between this homemade sour cream and what you buy in the dairy section. Store-bought sour cream is cultured with specific strains of lactic acid bacteria. Commercial producers also add natural stabilizers for consistency and shelf life.
The kind of sour cream we’re making here is called acidified sour cream, and it couldn’t be easier! It doesn’t need fermenting. Instead, we’ll use vinegar, allow it to rest on the counter for 4 hours, then sit in the refrigerator for at least 6 hours. So while it is very easy to make, you need to plan ahead so it has enough time to thicken.
Homemade Sour Cream Variations
For extra tangy sour cream, you can use lemon juice instead of vinegar, or add a third tablespoon of vinegar.
Tips for Success
It’s very important that the vinegar gets mixed throughout all of the cream. If any cream is left untouched by the acid, it won’t thicken properly and will leave the sour cream runny. It will still taste good, but the texture will be thinner.
