To make buttermilk at home, you can create a simple substitute by combining milk with an acid like vinegar or lemon juice. Here is the basic method:
- Add 1 tablespoon of white vinegar or lemon juice to a liquid measuring cup.
- Fill the cup with milk (whole milk or any milk of your choice) up to the 1-cup mark.
- Stir the mixture and let it sit for about 5 to 10 minutes. The milk will curdle slightly and become somewhat thickened and sour, resembling buttermilk.
- Use this homemade buttermilk substitute in your recipes as needed.
You can adjust the quantities proportionally for smaller amounts, for example:
- 1/2 cup milk + 1 1/2 teaspoons vinegar or lemon juice
- 2/3 cup milk + 2 teaspoons vinegar or lemon juice
This method works well for baking and can be made with dairy or plant-based milks, making it suitable for vegan or dairy-free diets as well
. If you want to make traditional cultured buttermilk, you would need to ferment milk with live cultures (from store-bought cultured buttermilk or sour cream) at room temperature for 24-36 hours, but the vinegar/lemon juice method is quicker and effective for most cooking purposes
