Vinegar to Milk for Buttermilk
So, how does it work? Essentially, when you mix milk with vinegar (or lemon juice, for that matter), the acidity of the vinegar causes the milk to curdle and thicken, creating a texture that's surprisingly similar to buttermilk. This process is called acidification, and it's a total science-y miracle!
Now, I know what you're thinking: "But won't it taste all vinegary and gross?" Fear not, friends! The amount of vinegar needed to make this magic happen is so small that you won't even taste it in the finished product. And trust me, the end result is well worth the tiny bit of effort it takes to mix it all up!
