Start with a clean glass jar or container that can hold at least 4 cups of liquid. Make sure it is sterilized to ensure the success of the culturing process.
Pour 4 cups of whole milk into the jar. Use whole milk for the creamiest results, but 2% milk will also work.
Add 4 tablespoons of store-bought cultured buttermilk to the milk. The cultured buttermilk serves as the 'starter' and will introduce the necessary live bacteria.
Stir the mixture thoroughly with a clean spoon to evenly distribute the starter buttermilk into the milk.
Cover the jar loosely with a clean lid or a piece of cheesecloth secured with a rubber band. This allows air circulation while keeping contaminants out.
Place the jar in a warm, draft-free area of your kitchen, ideally where the temperature is between 70–75°F (21–24°C). Let the mixture sit undisturbed for 12–24 hours.
After 12–24 hours, check the consistency of the buttermilk. It should be thickened and have a tangy aroma. If it has not thickened, let it sit for a few more hours in the same warm environment.
Once the buttermilk has fully cultured, give it a gentle stir, cover it tightly, and refrigerate it. It will thicken slightly more as it cools.
Store the cultured buttermilk in the refrigerator for up to 2 weeks. Before using, give it a quick stir, as natural separation may occur.
