How to Make Buttermilk at Home

Buttermilk is a common ingredient in foods from around the world, and while it's been a key staple in many classics, it's making its way into some of the current food trends. While most of us have likely enjoyed a stack of buttermilk pancakes, there's still confusion about what buttermilk is exactly. In essence, buttermilk is a pale yellow liquid that's created during the process of churning butter. It's typically fermented, producing a lactic acid content that yields a slightly tangy flavor and a thick, creamy consistency that's ideal for baking.
