Buttermilk Substitutions

Flavor: Plain yogurt has a tangy flavor similar to buttermilk, making it one of the best 1:1 substitutes. However, depending on the brand and type of yogurt, it might have a mildly sweeter or more pronounced tang than buttermilk.

Texture: Since yogurt is thicker than buttermilk, it can make batters slightly denser and creamier. This can lead to moister baked goods with a little more body, especially in cakes, muffins, and quick breads. If a recipe relies on the liquid content of buttermilk, you may need to thin the yogurt with a little milk or water.
