DIY Cultured Buttermilk

Note: You can make larger (or smaller) volumes as needed. I use a ratio of one tablespoon starter for every cup milk with reliable results. Unless your culture was not designed to be perpetuated (some freeze-dried options fall into this category), you can reserve a bit of each batch to culture the next.

Some recipes indicate that you should pasteurize your milk (at 180°F) before culturing or at least warm it to 76°F. This step is entirely unnecessary, as store-bought milk is all pasteurized before it hits the shelves.
