Buttermilk vs Half and Half: What’s the Difference?

You’ve likely seen lots of dairy in your kitchen, like milk, sour cream, and heavy cream. Let’s focus on two special ones: buttermilk and half-and-half. They’re quite different! Buttermilk has a tangy smell and taste because it’s made by fermenting dairy and helps soften baked goods. Half-and-half is a mix of milk and cream. It’s creamier than buttermilk and has more fat, adding a rich touch to your dishes.

Traditionally, it’s the liquid left after churning butter, but commercial buttermilk nowadays is typically cultured. Its slightly acidic nature makes it great for tenderizing meats and adding moisture to baked goods, not to mention its role in balancing sweetness in recipes.
