What is Buttermilk?
Traditionally, it was the leftover liquid from churning cream to make butter. This is now referred to as traditional buttermilk.
What you buy in the grocery stores is now cultured, which is produced by adding cultures to milk during the fermentation process to simulate the lactic acid that would naturally occur in the traditional kind.
