Bulgarian buttermilk is a cultured milk sold in the United States. The US standard for cultured milk (21 CFR 131.112), which does not name this product, requires the milk to be pasteurised before the culture goes in and the finished milk to reach at least 0.5 % titratable acidity as lactic acid.
A short entry: the sources we found record only what is said here about Bulgarian buttermilk itself. Its own sources do not record how it is made, so the steps and scenes below are those of Cultured buttermilk, the closest documented fermented milk ferment, shown as a guide to the method, not as a record of Bulgarian buttermilk.
