Homemade sour cream is one of those simple kitchen staples that’s incredibly easy to make, yet tastes so fresh, creamy, and delicious.
All you need is 1 cup of heavy cream and 2 tablespoons of buttermilk. Mix them together, let the mixture sit and culture, and you’ll have homemade sour cream ready to enjoy. It’s perfect for spooning over tacos, baked potatoes, chili, or adding to your favorite recipes.
Ingredients
- 1 cup heavy cream
- 2 tablespoons buttermilk
Instructions
- Pour the heavy cream into a clean glass jar or bowl.
- Stir in the buttermilk until well combined.
- Cover loosely and let it sit at room temperature for about 12–24 hours, or until thickened and pleasantly tangy.
- Once thick, give it a good stir and refrigerate until chilled.
- Store in the refrigerator and enjoy within about 1 week.
That’s it! With just two ingredients and a little patience, you can make creamy, tangy sour cream right at home.
